1. Jack the car up on Axel stands/ramps or if you have access to a pitit will make life a little easier. 2. You need to remove the splash guard underneath the car so you can seethe back of the gear box. 3. Drain the gear box of oil which will require a special tool which youcan get for £10 from Draper Expert 1/2 Square Drive Drain Plug Key For VW Or Audi63476 Draper Hdpk1. 4. Remove the electronic cable that connects onto the ECU that protrudesout the back of the back of the gear box. 5. The back of the gearbox has 12 torques holding the cover in place.Once you have removed most of them you will need to remove the rear enginemount to get at the last torque bolt at the top of the gear box. 6. Support the gear box with a trolley jack so you can lower the gearboxto get at the last few torques. 7. The rear engine mount can be slid towards the back of the car so youcan get at the back of the gear box. There is a couple of other bolts that youwill need to remove that hold the ECU cable in place. 8. Once you have all the torques that hold the gearbox in place thecover can be slid off. 9. Once the cover is removed be careful not to bend the metal gasket asit can be used again as long as it's not damaged (Audi would probably changethis along with the ECU seal). 10. Once the cover is off you can now see the ECU which is held in placeby 3 torques or Star bolts. 11. After the 3 torques have been removed you can then slide the ECU offbut be careful not to bend or tilt it as you remove it from the gearbox as ithas guide rails made of plastic which can break easily.

Yes All the above except I put my car on 4 wheels laid flat which is very stable. I removed and replaced the gear oil. I can't remember how much oil was taken out and no I didn't manage or knew how to empty the torque converter but I drained the Gearbox Sump and refilled it with the exact quantity I removed and added a a tiny amount of Lucas Auto gearbox treatment by little amount I would say 100ml just to lube up the old I couldn't remove.

    Thank you for the solution to this query. It is very important to have technical knowledge regarding vehicles. With these easy steps, we can remove the ECU. It can help the users to maintain their vehicle. They can solve these small issues on their own. I want to thank you to the technical team that they are always working to find out the solution for technical issues. I also own a car so it helps me to resolve these technical issues. I am researching technical issues and writing articles. customessaysservice is the best writing service provider which is helping me in my projects.

Replacing crown and pinion for audi a4 2000 multitronic

i suspect a LAY SHAFT BEARING but without a drive i couldnt say ,if its the pinion and crownwheel then i doubt this but it just needs setting up to a wiggle woggle on the backlash this is achieved by moving the crownwheel in or out of mesh with the pinion by adjusting the cap bearings ,but removing this gearbox and playing around with it on advice of who knows who is not advisable ,with it on the bench in front me i can do this adjustment with my eyes shut and just feel it but its taking it out for starters ,now this tiptronic type box with the paddle controls or whatever uses hydraulic transmission oil in the gearbox which doesnt do the crownwheel any good at all as EPoil is needed for this and it has the same oil as the autoboxes ,best advice is to find one in the scrapyard and just change it complete.Like the early minis with automatic gearbox and the engine oil running through the lot .URGH showing my age here i think

I own a Audi a4 multitronic 2005. Recently i'v had the PRND flashing either individualy or all together and I think it's not going through all the gears and an intermittent failure to engage reverse gear,...

I'm having a similar problem with my '05 A4 Multitronic with 75,000 miles on clock. PRNDS lights are all blocked out but not flashing (which I believe is worse). Car is driving ok after I had the EGR valve replaced by dealer at cost of £454. Dealer quoted me a further £1,077 to fit new gearbox ECU. Found a few websites that claim to be able to repair the ECU, best one seems to be www.BBA-Reman.com who quoted £169 +VAT + carriage. You do however need someone to take off and fit repaired ECU, had quotes ranging from £150 - £250 + £60 for 6L of new gearbox oil. However, I have been told by 3 independent garages that specialise in Audi's, BMW's & Merc's etc that they cannot be fixed, so I'm a little sceptical. To summarise the cheapest quote I've had for a new ECU fully fitted is from a garage on Tyneside (where I live) called Swift Motors 0191-2140056 who said they'd be able to do the lot for £860. Only bought car in February, absolutely love it, but sick as f**k at this unexpected cost which I can't afford. Had to take payment holiday from mortgage to cover the costs. Should have stuck with my old Ford Focus!! If anyone can offer any other tips I'd like to hear.

Audi dash lights

If it is the display for the gears flashing, this indicates a fault with the gearbox system, this is more common on multitronic gearbox's
