Front lower track control arm

Followers

November 8, 20205 yr

I have an A6 Avant Sport 1.9tdi 2002. I am replacing the front suspension arms. All went well until I found that the front lower track control arms I have been sent have a ball pin with 20mm at small end of taper, whereas mine needs 16mm. Every other dimension of the arm & bushes seems identical. My old arm carries the Audi part number 4B0407155 and that seems to be a very elusive part number. However there are plenty of sources for arms with 16mm pins although the OEM part numbers they quote don't end in 5.

What is the best solution -- I don't want to spend a fortune on an 18 year old car!!

Thanks, Judsonig

It sounds like you e been sent the wrong part. The correct one for yours is the 16mm whereas the new ones which are incorrect are designed for the rs6 and s6 I believe. Might be worth you sending them back and getting them to send out the correct part.

I got a weird one. I'm fairly car literate and I'm usually able diagnose and know the problem to pull in to my local independent shop and tell them this and this need to be fixed and replaced. But this has me stumped. I have a 2016 Q5 2.0 engine that went bad with carbon deposits yada yada... So I stepped up got a new motor from Power Engines it came all crated up they were super helpful pleased with them. My mechanic moved all the bits and reattached them to the new engine from the old.

Gearbox service

Pete A · yesterday at 11:23 AM1 day

Good day all, I have a 2.0 TFSI with the ZF 8 speed auto ‘box which I intend to get serviced within the next couple of months. Is this just an oil and sump/filter change or is there mechatronic seal (for the wiring) on these? I’m going to get the oil changed in both diffs and the transfer ‘box, is there anything else within the drive train that needs looking at while it’s on the ramp? Mileage is 65,000 miles.

Titanium · Saturday at 12:12 PM2 days

Although not required as yet, I'm thinking /looking ahead and wondering about servicing costs. Like all Audi dealers/dealerships it's best I guess to have your car serviced by Audi but I'm sure the price/s will not be as cheap as independents? (Yes they would have to use genuine parts). Does this forum show recommended companies i.e good garages that will be cheaper but carry out as good work as Audi. I look forward to guidance. Thank you.

A6 c5 allroad seats

matty_s6 · May 27May 27

Due to turning the car into a track car, the seats and door cards are no longer needed. They are green and grey with wooden look trim. They need cleaning up and the rear seat is damaged at the top plastic part but it still locks in place. £200 ono with the wooden look trim. Collection only though from north west, near Preston. I also have other trim pieces from the c5 saloon that are now out of the car.

Audi S6 track car build

matty_s6 · May 27May 27

Ok, after completing the gearbox swap and driving the car for a few months, things have started to fail. The speedo doesn't work, even after putting in a speedo pickup in the gearbox, sensor and repairing the wiring. The electric windows all stopped working. The central locking won't work. The airbag and abs light work as they please. My next step is to strip it and turn it into a track car. I know they are not known for being great on a track, but I will try anyway. The seats are very heavy, so

Hi, I’ve recently got a second hand A1 2012 S-Line 3dr. I took it to Halfords and they have advised I have a blocked Air con. I’ve just replaced the the air filter and cabin filter as they were past due. Does anyone know if I can unblock the A/C myself and if so how to do it and what I’m looking for. Many thanks in advance

Would You Add Bluetooth to a Classic Audi?

Baltic Retrofit · yesterday at 11:42 AM1 day

Recently had a few of these Audi Gamma & Delta on the bench for a Bluetooth retrofit. Personally, I think this is one of the best upgrades for a classic car You keep the factory radio, 100% factory look, but gain modern Bluetooth functionality. Curious what others think. Do you prefer keeping everything completely original or making hidden upgrades that improve usability?

Stef-Wulfhere · July 13, 20241 yr

Hi, my Audi MMI MBI (i think glovebox unit) speaker sound seems to be failing, everything seems to work, there is just no sound. sometimes it works but this has become increasingly rare. It only seems to work once every 4 weeks ish now. I resorted to a Bluetooth speaker but its a bit rubbish to be honest. I believe it probably just a few PCB components that have failed. I'm looking for any recommendations for a repair service. Thanks all

Having problems working out my fuel tank capacity -

Steve132 · Saturday at 09:12 PM2 days

Hello I am a new Audi owner and have a A6 40tfsi C8 Facelift Sport Saloon. The car has been everything I hoped it would be -quiet and smooth on the road with enough power to keep me happy in retired life. When I first received the car it had a quarter tank so when it reached only 30 miles of fuel left I filled it up to the brim but could only fill 53 Litres. I have again run the car to show only 30 miles remaining and again can only fill 53 Litres before the tank is full I have checked th

Hi all, New user here, hoping someone can help me out with this 😁 I'm trying to map out some extended diagnostic pids (uds mode 22) for my a4's ECU (Bosch EDC17).

1992 Audi 80 Piston Ring replacement

Mike651 · Saturday at 08:56 PM2 days

Hi all, I’ve just got my hands on a 1992 2.6 v6 Audi 80 in good condition (considering price) and have done what most buyers do first and changed the oil. It was very murky and smelled strongly of petrol so I decided to flush. 4 times I flushed and drained each time after letting it run for around 10 minutes. The oil would not clear up and was persistently murky and fuel smelling. After doing a bit of my own research I believe my piston rings may be worn and allowing excess smoke and fuel into t

Having trouble with charging at public charge points.

Andy Dodson · Saturday at 06:51 AM2 days

Hi all On a bit of a road trip, have planned the route around type 2 charge points. I can use my own charge cable ok, but even though the last energy supplier took a holding deposit, the charge failed to initialise and the deposit returned. It has happened several times now and makes me think I have a setting wrong in the car. Any help or advice will be greatly appreciated. I will post details of the trip at a later time in the appropriate thread. Andy

Adblue fault no restart after 650miles, Error codes P20BC,P20E8

Doctor786 · October 16, 20223 yr

I had this message 4 months ago as well but simple turn off the engine and restart again solved the issues but the same issues has come back last week but this time with engine management light as well. It started the countdown to 650 miles and when it got to 550 miles some how it disappeared but came back after I did almost 300 miles. So countdown is down to 600 miles again at the moment. I am getting 2 error codes. P20BC : Reductant heater "A" control circuit high P20E8 : Reductant p
