VW DSG Gearbox problems

[robertcorran]

Hi Folks

I'm new to PH so be patient, I have a VW Golf Match 1.9 tdi and it has a triptronic DSG gearbox, it has started sticking in 2nd and 3rd when in the drive mode, on some occasions it drive normally up through the gears 1 to 6 and changes up and down according to the driving criteria. Also it keeps brining up random warning lights on the dashboard even though it is driving well.
It drives perfectly well in Manual mode which makes me think it is not a major mechanical problem, but not being a mechanic I don't know

Has anybody else had this problem and if so what is the fix for it PLEASE HELP its driving me nuts

Firstly to save you confusing if your searching, tiptronic and dsg are two totally different gearboxes. You more likely have a dsg box although older Golfs had tiptronic as well. All recent VW cars will log faults via the ECU and a dealer or any decent mechanic will be able to read these faults, this is where to start. Also how long have you had it, has the gearbox been serviced to recommendations, i.e. Fluid and filter changed?

Cupramax Thanks for your feedback and advice much appreciated, cars hey what a pain in the backside at times, it is a DSG box you are right which can be driven in either auto or manual mode, I had it serviced recently and as far as I am aware it hadn't been done before I could be wrong, it is 2007 Model

Yes, 2007 will be DSG. The gearbox oil is supposed to be done every 40k or 5 years i think. Your first point really is to get the fault codes read and then work from there as to whats wrong.

Did they swap out the oil in the dsg box whilst it was serviced?

If so id do that first, cures a lot of dsg issues

[robertcorran]

As far as I am aware they stripped the Oil out replaced it with new and changed filters etc I really am at a loss with this because the car runs great most of the time

[robertcorran]

Here we go guys, when I set off it will drive to 3rd gear and get stuck, I then manually move it up through the gears to 6th, once in 6th gear run it for a couple of minutes then knock it into DRIVE MODE(Auto) where it then proceeds to drive normally up and down the gears. It brings up Fault lights for ABS and the Anti skid but the car is running well, it's obviously an intermittent fault and I'm convinced it's not a mechanical fault as it drives through the gears normally its just the initial issue from start up

[redtwin]

Does the invoice for the service specifically state that the gearbox oil was changed and that the oil they used was the correct type?. I would want to *know* the gearbox was serviced, not just think it was.

Warning lights for ABS and traction control would lead me to think you have a wheel speed sensor issue and if the gearbox ECU couldn't be sure of the car's speed (due to faulty speed sensor) then it wouldn't know which gear to shift into hence becoming "stuck" in a gear.

As mentioned, take the car to a good garage with diagnostic equipment and mechanics that know how to use it. You can do this before or after you have assured yourself that the gearbox has been serviced correctly.

[robertcorran]

Redtwin - that's great thank you for your input, the garage that serviced the gearbox used VW parts and stated on the invoice the oil was changed and the correct type used so I don't think that's the issue. What you said made sense to me, and not being a mechanic to me that's good!

[philmots]

I was going to say what 'Redtwin' did..

Sounds like you've an abs/wheel speed issue which is causing issues with gear section.. I'd suggest sorting that will sort the gearbox.

Echo comments re servicing too.

Guys

Thanks for your help I took it straight to the garage last night when the fault warning lights came on again (It has been an intermittent fault) anyway the rear left wheel speed sensor has a fault on it, they are ordering one today and I'll let you know if it does the trick, like you guys I suspect it will

Thanks for your help along the way much appreciated

[redtwin]

Fingers crossed for you, looking forward to hearing the outcome.

[robertcorran]

Hey guys it was an intermittent fault with the Left Rear Wheel Speed Sensor and a wheel bearing needed replacing also, thank you all so much for your advice. the golf is back to it's best thank god I didn't need to fork out for a Gearbox refurb etc

[redtwin]

Love a happy ending.

[Chr1sch]

thank god i was fearing the worst with this i must admit!

[robertcorran]

Thanks guys

Thanks for posting up what was eventually wrong, worrying the more tech that gets stuffed in cars, with a manual box you probably would never have noticed.

[GroundEffect]

Sensible outcome. It did sound control related.

[Limpet]

Marvellous result, but does make me wonder what a less scrupulous garage would have "found" and charged for.

Yep, always good to get a conclusion!

You'd probably have noticed that, even with a manual box.
