So yesterday my Audi A3 2.0 tdi SLine dsg 2006 auto decided to play up. The gears started being funny and wouldn’t auto shift up as it usually should. 

Today it had been looked at by my local garage who has basically said there is an issue somewhere with the gearbox but it’s not worth spending any money on. 

As far as I’m aware this car is worth 3500-4k so I’m willing to chuck £1k at it. Surely something can be done with this? Has anyone had any experience with having a new gearbox fitted or had the existing one removed and fixed?

Any advice would be great. 

 I reckon you would be lucky to get even a secondhand gearbox from a breaker for £1000 let alone a recon box.

As far as I’m aware you are looking at around £2000 for a new box to be fitted.

out of interest has the gear box oil and filter been serviced as this could help the situation. It would cost roughly £225 to be done and you should take it to an Audi specialist to make sure it’s done properly.

I have now sorted to car. After being told it was going to cost thousands and that I need a new gear box, it was just the mechatronic unit. 

 

I removed this myself, sent it to be repaired for £250+ VAT and then refitted myself. Also replaced gearbox oil and filter myself at the cost of £60. 

This solved the problem and 3 weeks later still going strong! Just goes to show garages just tell you any old ********

good result m8 happy to see your back up and running 

Glad to hear it. Where did you send the mechatronic unit for repair?

Sent it to ECU testing. They charge £250+ vat if it’s repairable or a £50 fee if they can’t. Car was worth £500 in its current state so didn’t have much to lose!

Fantastic result!

out of interest was you having any problems with the car before it became apparent it was the gearbox?

the reason I ask is my car has started to feel strange at times and I had my garage look at it and they said it could be the start of gearbox problems but no fault codes are being thrown up at the moment.

The flywheel has been rattling which I’ve known for a while and needs changing. Other than that it did start being sluggish pulling off more than normal which seems to be better now. Kind of just happened out of the blue.
