"The Digestive" Weekly roundup 24th May - 31st May 2026 As we close out May, this week’s forum activity has been buzzing with discussions spanning from technical woes to exciting projects. Let’s take a closer look at what’s been happening across our Audi models! The Audi A4 (B9) Forum saw a particularly lively topic regarding a 'brake servo restricted' warning that a few members, including Stevie84 and A-D, have been grappling with. The general consensus is that this may be linked to sensor faults, which is concerning for a relatively new car. Peter1028 shared a frustrating experience with diagnosis and repair costs, suggesting that the issue might actually be software-related. As many have faced extended wait times at dealerships for diagnostics, it reflects a pressing need for better warranty coverage on such faults. Moving on to the A6 (C5) Forum, Steve Q is deep into an ambitious project involving engine removal and inspection. Supported by forum members like Stevey Y, who offered tips on suspension upgrades, it’s a great example of camaraderie in our club. They’re tackling challenges like seized calipers, but with encouragement, Steve is steadily enhancing his mechanical skills. In the A6 (C8) segment, JRUK has been on a quest for a genuine 20” spare wheel and tool kit. After some troubleshooting, it seems The Wheel Shop might be the answer, although fitting adjustments are still a concern. Cliffcoggin and others provided valuable feedback, proving that our members are always ready to lend a hand. Meanwhile, Adam raised an important question in the A3 (8P) Forum concerning intermittent clutch pressure loss. Responses from Cliff and Gareth underscored the risks of air in the system or faulty seals. Adam is now leaning towards managing the issue rather than opting for costly repairs, reflecting the financial realities many of us face. Over in the A6 (C7) Forum, Jezza20 discussed the persistent EML light and P2000200 fault code. Stevey Y brought his wealth of knowledge to the table, with repair costs potentially reaching £4,000—a sobering reminder of the importance of thorough diagnostics. The advice to replace the EGR cooler remains a significant investment, but one that may prove essential. For those considering an Audi A6 C6, X3VSO initiated a helpful conversation on pre-purchase checks. Members highlighted the necessity of a full MOT, service history verification, and the utilisation of diagnostic tools like VCDS. These discussions not only prevent potential pitfalls but also foster a spirit of responsible ownership. Our A3 (8Y) Forum has also been buzzing, with Joe6 successfully navigating a rear wiper replacement on his 2023 model, thanks to a detailed guide from AlanH. This kind of knowledge-sharing exemplifies the spirit of our club. Lastly, it's been great to see recent discussions about features in newer models, like the oil temperature reading on Francis007's S5 Avant HUD, raising questions about uncommunicated software updates from dealers. Want to join the conversation? We warmly invite all members to visit the forum, share your tips, ask questions, and upload photos of your vehicles. There’s always more to learn and share within our fantastic community. Until next week—safe driving and enjoy your Audis! Best, The Audi Owners Club Team Audi A3 (8P) Forum Digest Clutch pressure loss then comes back? 13 replies Adam raised concerns about intermittent clutch pressure loss in his Audi A3, following repairs to the master cylinder and pipe. Cliff and Gareth offered insights, with Cliff suggesting the possibility of air in the system or faulty seals, while Gareth highly recommended using quality parts like LUK for repairs. Despite multiple bleed attempts, Adam noted that the problem persists occasionally, and he is currently opting to manage it rather than undertake costly repairs, acknowledging that he’s already had substantial mileage since purchasing the car. 3.2 overheating issue 7 replies Rybrook raised a concern regarding persistent overheating issues in his Audi, specifically with the DSG system displaying the dreaded "block of death" in hot weather. After draining the coolant and flushing the DSG oil cooler, he identified the problem as a faulty plastic water pump impellor, which he replaced with a more durable metal one. Cliffcoggin expressed interest in the replacement source, to which Rybrook promptly provided a link for next-day delivery from Parts In Motion. The community rallied to share insights, demonstrating the collaborative spirit of the forum. Audi A3 (8Y) Forum Digest Rear wiper replacement 7 replies Joe6 initiated a conversation regarding the removal and replacement of the rear wiper on his 2023 A3 8Y, expressing concerns about damaging the plastic arm. AlanH provided a detailed step-by-step guide for the replacement, emphasising the importance of caution and protecting the glass. After experimenting with various methods, Joe6 successfully figured out the process, acknowledging the initial difficulty but ultimately finding it easier than expected. Steve Q joined in to congratulate him on resolving the issue. Audi A4 (B7) Forum Digest Ai the mechanic? 6 replies Bedders raised concerns about his 20-year-old Audi A4 2.0 TDI, citing a lack of power and juddering issues. Cliffcoggin advised seeking out an independent VAG specialist for a thorough diagnosis using proper code readers, while spartacus68 emphasised the importance of budgeting for essential repairs without overwhelming costs. Following this guidance, Bedders has scheduled an appointment at a local garage with VCDS capabilities next Thursday. Audi A4 (B9) Forum Digest Brake servo restricted 714 replies · 15 files Stevie84 initiated a discussion regarding a recurring "brake servo restricted" warning on their Audi A4, raising concerns over potential sensor faults in such a new vehicle. A-D echoed this sentiment, noting that multiple owners are experiencing a similar issue—many after infrequent use during lockdown—and highlighting the lengthy wait times for diagnostics at dealerships. Peter1028 shared a distressing experience with an exorbitant quote for repairs, suggesting that the problem could stem from a software issue rather than hardware failure. The consensus indicates a frustration with Audi's response and potential oversight regarding warranty coverage for this fault. Audi A4 B9 - 2019 35 TFSI Petrol 5 replies Navs747 raised concerns about a coolant leak in their 2019 Audi A4, noting a drop in coolant levels and a pinkish liquid around the engine area. Cliffcoggin advised checking the reservoir cap and examining the engine while hot for signs of leakage. Fortunately, Navs747 later identified a hairline crack in a connector as the source of the issue. This diagnosis highlights the importance of thorough checks and proper observation during troubleshooting. Audi A5 Club Digest Roof opening from key 5 replies BookerSussex raised a query about the roof opening feature on their 2013 A5 convertible, noting that it doesn’t respond to the key. Stavros offered a helpful tip, suggesting a technique involving a double press of the unlock button: a quick press followed by a sustained press to operate the roof. Although some debate ensued regarding Stavros's recent activity on the forum, it ultimately highlights a useful method for fellow Audi owners facing a similar issue. Oil temperature showing up in HUD 5 replies Francis007 initiated a discussion regarding the unexpected appearance of oil temperature on the Heads Up Display (HUD) of his new 2026 S5 Avant. ScottyB10 contributed by suggesting the possibility of a recent over-the-air update causing the change and noted the absence of warnings in the system. After contacting his Audi dealer, Francis007 learned that a software update may have enabled this feature without notifying UK dealerships, possibly related to the rollout of the new RS5 models. Members are encouraged to check if this feature appears in their vehicles. Audi A6 (C5) Forum Digest I've bit the bullet 65 replies · 4 files Steve Q has embarked on an extensive project to remove and inspect the engine of his Audi A6, with help from a friend studying mechanics. As the pair work through various component replacements, they face challenges such as seized calipers and rusty springs. Members like Stevey Y provided valuable advice on selecting suspension upgrades and dealing with potential corrosion issues, leading to a meaningful consensus on the Bilstein B6 shocks being a preferred option for the desired ride quality. Overall, the participants supported Steve's hands-on approach, encouraging improvement of his mechanical skills for a successful restoration. Audi A6 (C6) Forum Digest What to check before I buy? (C6) 9 replies X3VSO kicked off a discussion regarding what to check before purchasing an Audi A6 C6, particularly a 2010 SE model.

They also mentioned potential concerns such as common engine issues and the need for regular transmission servicing. Ultimately, they advised thorough checks and emphasised caution when dealing with sellers to avoid potential pitfalls. Audi A6 (C7) Forum Digest P2000200 10 replies Jezza20 started a discussion regarding a persistent EML light and a P2000200 code on his 2014 Avant Ultra, highlighting issues with the DPF and EGR cooler. Stevey Y shared his extensive knowledge, detailing the costly repairs needed, which could range from £1,600 to over £4,000, and advised caution when considering in-situ cleaning methods. The consensus among members indicates that replacing the EGR cooler is often necessary, yet it’s a significant financial commitment with no guaranteed resolution to the issues. Mismatched tyres 7 replies RichD raised a concern about mismatched tyre sizes on his 2018 A6 Avant Quattro, noting the fronts were 225/45R18 while the rears were 245/45ZR18. Cliffcoggin pointed out that, while the widths differ, the diameters remain safe, although mismatching may affect handling on Quattros. Spartacus68 suggested verifying the handbook for the correct specifications, and Magnet advised double-checking what was originally fitted to the car. A consensus emerged that RichD should confirm the original tyre size before making any changes. Audi A6 (C8) Forum Digest Sourcing a genuine 20" spare wheel/tool kit for A6 C8 S line 19 replies JRUK is on a quest for a genuine spare wheel setup for his Audi A6 C8 S line but faces challenges, particularly with Audi not supplying a space saver. Dalswinton suggested The Wheel Shop for a high-quality alternative, which JRUK later confirmed they could provide, though it posed a fitting issue in the boot. Cliffcoggin offered insights on potential fitting adjustments, but the concerns about stability remained unresolved. New member Binnedit also joined, inquiring about compatibility with different wheel sizes.
