1.9 tai tiptronic reverse issue

[5835carter]

Hi all, I know you have probably been trough all of this before but I have read and read forum after forum and haven't actually found an answer although I have an idea....

Reverently bought my superb from from auction and shortly after purchasing noticed I have a reverse issue. It will go into reverse, and will crawl/roll backwards but as soon as I accelerate it will loose drive then when returns to idle it will start to reverse again

I have read a lot about reverse drum but not 100% sure this is my issue as I do get reverse, I have done a code scan and only got p1119 from abs control unit 'gear recognition signal intermittent. Could this be an issue due to a faulty valve/pressure regulater or is it reverse drum??

Should it be due to the reverse drum has many people changed them or even know where I can purchase a drum from?

Thanks in advance, James

Mine was the reverse drum apparently; if I put it in reverse and had foot on brake it would "kargaroo" against the brake.  Don't know how to tell the difference between the two - I guess if you're stripping it down it would be best to do both.  I think the valve repair involves reaming and an oversize part.  But most of that is reading I did to educate myself - I copped out and got the whole thing done by a specialist.  I never had any codes, but it never failed as badly as yours has.

 

5HP19 drum kits are on ebay, I think aftermarket.  Sussex Autos can supply all genuine parts:

I guess the drum failing can cause all manner of manifestations depending on whether the chunks have fallen off and distributed themselves, or are still clinging on and just leaving the clutches loose.

Thanks for the reply and the link.. If you don't mind me asking how much was your repair? Cheapest I've been quoted is £650 but then extra if any clutches are found to be worn :/

I had the whole shebang done two years ago as the car was still worth a little - cost me £1500 at the time.  They rebuilt the torque converter too as apparently once the fluid is contaminated the converter just becomes a store of problems for later.  Or so they said.  I was reasonably happy - the car is still going well 55K miles on, but I did have to go back pretty much immediately as it wasn't changing down to 1st smoothly enough (despite being told that it would "learn" how to do that right... hrmmm.).   Plus I was left with a misaligned exhaust which took a couple of garages to work out why I was getting a banging on acceleration occasionally.  

 

£650 sounds very good - where is that?  I don't think all the clutches are much money in the scheme of things.

 

If mine goes again I don't think I'll be able to justify what I spent on it last time.

Hopefully the aftermarket parts are a bit stronger then the original for you.

I didn't think it was too bad myself but I've only just bought the car for £1560 and £650 just seems a bit like a kick in the teeth. The £650 repair was if I took the gearbox out and re-fit, and then it wasn't an overhaul, just a reverse drum supply and fit with new filter and oil. Thats from a bloke called John in portway, redditch. He doesn't advertise, I got hold of him via my snap on dealer. I do have his number thought if anyone wants it

I think I'm going to call up Sussex auto for the drum/kit and have a go at doing it myself. Cheers for the help jimbof

You want to buy the factory manuals if you're going to give it a go, there are gotchas which if you don't follow you end up killing the transmission fluid pump drive. Skoda ERWIN is where you can get the docs. Costs about £6 to get an hours time, and you can get all the docs for the car in that time.

I am happy to say, reverse is now fixed. I found a second hand gearbox on eBay and for £350 posted so bought it but when it was delivered the casing was all smashed. after a lengthy chat with the supplier, they refunded me £250 and said I could keep the box. after reading so many posts and watching YouTube videos I felt confident to undertake the repair myself. I stripped the damaged replacement box, it wasn't a bad job, just time consuming. I removed my gearbox from the car and proceeded to strip that but found absolutely NOTHING wrong with it. I took the gearbox to an auto specialist in bits and he charged me £250 to test and check everything. he put it all back togather and the only thing he found wrong with it was a worm o ring in the oil pump. refitted the box with new oil and filter and it works. I am so pleased with it, the gear changes are amazing, hardly noticeable. if anyone else has an issue with reverse, I have got complete internals spare for a 5hp19 eyf gearbox
