Gearbox in my A3 had been notchey since purchase. Dawned on me today this is no longer the case. I may still carry out a gear oil change. Shouldn’t temp fate but I do like a free fix 🤔😁

Got this sorted. Had to get rack refurbished. Company said that ecu on rack read and faults were water damage and voltage inconsistency. Found broken wire on loom travelling over back differential. Got this replaced and rack fitted and after 8 weeks we are out and about again 🤦🏼

I had a garage do it as it’s not easy on a drive! But forum discussions at the time (if you do the job yourself) suggested blanking off the air pipe and running the pump to check for leaks (dont run it for more than 1 minute in ten) it’s just not designed for it and will likely burn the motor or compressor seals. if you can pressurise it another way to test, I’d do so.

PS; it’s not really safe to drive at all TBH with collapsed suspension on 1 side, and defo not at any speed over 30. My Allroad had the tyre rubbing on the wheel arch when it blew a bag. sorry!

I agree with Steve, one of the bags has probably gone. best to get it sorted asap as the pump will keep trying to push air into that side and it’s simply not designed or able to run for long periods, it will fail in fairly short order (been there, done that!😔), it takes the 40A Relay with it too. ‘oem’ parts are made by non Audi specialist manufacturers/suppliers, eg, air pump is same as used by Mercedes, RR, Range Rover, Bentley, etc. so I bought a pump from the US manufacturer for £300 instead of £1300 from Audi. single Audi airbags arent too bad, but if it’s more than one, I’d look for the US made upgraded versions that used to come with a lifetime gaurantee and replace all 4. depends how long you plan to keep it tbh.

I'd suspect that the bag isn't inflating and changing it is the only option.
