Don. If you can smell the coolant it must be escaping somewhere, though at a mere 1500 miles per year the loss may be so small that you don't get a warning before the garage tops it up during annual servicing.

Thanks for the information which suggests that the old caliper was indeed at fault, even if nothing was visibly wrong with it.

The more you drive a slipping clutch, the worse it will get, causing high fuel consumption, and eventually the car will not move. Do you have good breakdown insurance?

The stop/start system may be present in your car, but if the battery is defective it won't work. As Steve said, find out if the system is installed. Whatever type of battery you fit ensure it is coded to the car.

That makes sense, and fits Audi's push for subscription services.

Hi, this may or may not be of interest to anyone, but I have finally managed to fix the issue about a month ago. Here's the summary: Electronic parking brake on the left side stopped working more than six months ago. There was a warning on the dash ("parking brake malfunction") accompanied by a loud beep every time I turned the ignition on. I have unplugged the wire from the electric motor on the left. The same warning remained on the dash. Parking brake on the other side was working correctly. Then life and other things got in the way and I did not do anything to rectify the issue, except for making sure that the wire does not dangle under the car and the socket on the electric motor is waterproofed (plastic bags and zip ties). I continued to use the car daily. I kept using the parking brake as and when required and it was still holding the car even on fairly steep inclines, even though it was only working on one side. I finally got some spare time and replaced the electric motor and also the plug with about 20cm of wiring. Apparently it is not unusual for this to rust and cause issues. I only bought the cheapest plug and the cheapest parking brake motor I could find on ebay (probably about £30 total). Fitted the parts, but the parking brake still did not work. As it happens it was engaging, but not disengaging. So in the end I replaced the brake caliper. Again, the cheapest one I could find, which was about £60. I replaced brake discs and pads at the same time, but only because they were quite worn (this was not related to parking brake issue). After I replaced the caliper the parking brake issue was resolved. The warning disappeared from the dash and I did not need to reset any faults with the code reader. Also, the parking brake is now almost silent when engaging/disengaging. To the point that when I first tried it after fitting the new parts I thought it was not working at all (it was fairly audible before). It has been about a month now and all is well. I almost miss the loud beep that accompanied the ignition being turned on every time when the fault was still present. PS. If anyone is replacing the rear brake discs, there are some videos and guides on the internet that tell you to remove the brake caliper carrier, but you can actually wiggle the disc out carefully without removing the bracket or damaging the disc.

thanks steve i have a journy down to sussex in 3 weeks would you advise a new clutch to be fitted as this has only happend and havent drove since

Hi it sounds like the clutch is either contaminated on the friction plate or on its way out. Steve.

Hi ring the dealers and ask if your car was fitted with stop start, you will have to give them your VIN and if its not equipped with stop/start you are away, only piece of advice is buy branded and not some random make of battery that is dirt cheap and won't last long, the battery will need to be registered to let the ECU know it has a new battery. Steve.

Hi yes but the new module would have to be coded to the car, try and find a local car audio specialist who will be able to offer a hybrid solution rather than get in to major removal of the existing unit. Steve.

Hi, this maybe a sill question!!! I need to change my Battery in my 60 plate Audi A3, the guy in the shop said there is 2 types, one for stop start car and a one without (big difference in price). My car dosent seem to have stop start, because it dosent do it!! But the guy in the shop says it can turn itself off!!! There is nothing on the current battery to say its a stop start battery !!! Guy in shop says if you use a standard one in a stop start in can effect the ecu, so some functions wont work correctly.... Any help would be appreciated...

Hi sounds like the Haldex unit in the rear diff is on its way out this would put the car in to limp as its controlled electronically by a module. Steve.

Hi at a guess you have no subscription to the emergency call system its just their way of badgering you in to subscribing again, try having the car scanned to remove it, if its anything like my Passat I had to delete it a couple of times and they now have the general idea, not subscribing so it has not ever come back in over a year. Steve.

hi all i have an Audi a4 2007 2.0tdi sline when in 5th or 6th gear the engine reves up when accelirating hard but is fine if you drive normal and all over gears are fine any ideas what this could be thanks

Hi no smell no light's on dash . Waiting for freind to plug in computer to get better idea. The noise comes and goes ,not heavy appears to be from rear offside .random clunking . Regards.

An impossible question to answer because you have not revealed the brand in question.

Thanks Scott. That's useful information.

Aftermarket brands you are considering Suheel?

Rs4 2013 aftermarket water pump would you trust part. Suheel

Welcome Don, My first port of call would be to return the car to whoever carried out the front end bodywork. If both horns were working prior to this then it’s reasonable for you to expect them both to work now - unless one was damaged - at which point it should have been renewed. Believed each to be behind the spotlights (if fitted) or the plastic grilles if not. Regards, Gareth.

I know the op might not be here anymore, but for others here: I recently had the chance to drive two identical specked 2024 A3’s, both built within a month of each other with identical speck, 1.5tfsi DSG, with very similar mileage. The only difference was one was running a set of new Bridgestone Potenza Sport, the other was on a new set of new Goodyear Eagle F1 Asymmetric 6. Both were on 235/35R19 V91 After driving for over a month on different road conditions both cars, the difference in tires was quite noticeably different. The Goodyear were noticeably quieter and felt more comfortable on our rough UK pot holed roads, the Bridgestones by comparison felt harsher and noticeably noisier, handling wise, not that they were pushed to their extreme, the Bridgestone felt better cornering in the dry, but I personally preferred the Goodyear in the wet on the bends. I was not expecting to notice much difference between the two, but a difference of tire brand made the cars feel completely different to drive on a daily basis, the Goodyear were far better for me.

Hi, One of the horns on my 2015 is not working. Just had some front end body work completed so maybe one got disconnected. Do I have to pull the bumper to service them? Please tell me there is an easy way to maybe remove some covers. Thanks, Don

Hi, My 2015 A3 has about 15,000 miles on it. Ever since I got it about 6 years ago I notice a faint coolant odor after a drive. Never had to add coolant. Someone told me that is common with this engine. Doesn’t really bother me, just annoying. I replaced the reservoir’s cap with no success. Appreciate any suggestions. TIA

Happy to share further photos if required.

Unfortunately the 2 websites given do not help. Does anyone have any other suggestions? I have tried ebay and the devices available are not suitable for my version of MMI. Is it possible to exchange the MMI module for one out of a British car?
