ssilversurfer Posted January 31 Report Share Posted January 31 Hi All, I'm after some knowledgeable advise if possible please!? I have a feeling this may be expensive :(! Yesterday my 17 plate Mk7.5 Golf R with (Mountune TCU and ECU maps) decided to give me the following serious faults: Loud bangs and jerks in shift change (irrespective of drive system), inability to engage drive when in 2nd gear for approximately 10 seconds - where the car just revs, sudden rev increase with an attempt to change gear, dropping from 5th to 2nd on slowing, then re-selecting 4th, 3rd, 2nd again a horrible mechanical clatter from the gearbox when reversing The car is almost undrivable at slow speeds but okay cruising - so I could get home at least. I have put an OBD reader on and the codes are P02FF and P26C6, which are showing nothing on the net. I called a couple of VW specialists and transmission specialists, where all but 1 refused to assist: The 1 transmission specialist told me it sounded like the mechatronics needed repairing. He would charge £200 to remove and replace it, but needed send it off to be inspected/repaired. Unfortunately he could not get me in until the the 10th Feb. I began investigating the issues last night and it seems there are lots of problems with the Tiguan DSG DQ381 and a few rather insignificant issues with the Golf R DQ381. Nothing like the faults I'm experiencing for sure. But, what I did notice is that my car is subject to a recall/global campaign for the DSG. I called my local VW garage this morning and they advised the recall was to stop a bolt in the hydraulic pump from coming loose and trashing the gearbox. They upload new TCU software if no faults are found. Someone did say on this forum this update reduces the torque and power to the gearbox to prevent the bolt loosening, but I'm not certain of this. Some owners on Audi forums have had holes blown out by the bolt in their gearboxes and still ended up forking out £7k for a replacement without a successful claim from VAG. VW told that me they would need my car to read the codes on OTIS before they could assess whether the fault lies with the bolt shearing (or whatever the global campaign is really about) and if so, then decide if the repairs would be undertaken by VW - considering the car is out of warranty (and of course has been remapped). For this I would need to authorise an hour with the technician at a cost of £120. So, really i'm in a dilemma about what my best options are: Do I keep my booking with the transmission specialist and just take the hit of a possible reconditioned mechatronics system and hope this will solve all the problems or, do I pay for the hour slot for VW to read the codes and await their decision as to whether they are liable, or not? I guess if I choose the latter, I'm only an additional £120 down if VW say the fault is not with them, but they may also admit liability and fix the issues at no cost to me at all. Or, do I take the chance at the transmission specialist and hope that this bolt hasn't sheared and it is only the mechatronic unit which needs repairing/replacing? I think in this case, my concern is the clatter when reversing, as I just don't understand why there would be so much mechanical rattle if nothing was broken. Or, is this another symptom of a faulty mechatronics? Anyway, that's my dilemma. Any advice would be greatly appreciated. Chris Quote Link to comment Share on other sites More sharing options...
Maprunner Posted January 31 Report Share Posted January 31 I’d be spending the money at vw. The transmission guy has diagnosed it over the phone….so he could take it out, send it away and you’ve got it back and it’s not faulty. Whereas if vw check it over properly, you may have some comeback with them. Think of it this way - would you rather chuck away £120 and have a possible warranty claim or £200 with the possibly the same issue as before.

ssilversurfer Posted January 31 Author Report Share Posted January 31 Good point Maprunner. Just waiting to hear if there is anyone out there that's had similar issues or could say whether this is just a mechatronics fault or worse perhaps.

Maprunner Posted January 31 Report Share Posted January 31 Good luck with whatever route you go….hopefully it’s a relatively “cheap” fix and nothing catastrophic! Quote Link to comment Share on other sites More sharing options...
ssilversurfer Posted January 31 Author Report Share Posted January 31 Thanks Maprunner, Hopefully if it is only the mechatronics, this should be around £600 after removal, fix and replacement. If it's a fault with the gearbox and clutch then this would run into thousands 😦 Quote Link to comment Share on other sites More sharing options...

When I brought my car to a local VW dealership for diagnosis of the noises I could hear in the cockpit that appeared transmission related, the only thing they told me was that there was a noise coming from the gearbox/transfer box (they weren't sure which and weren't going to open anything up), suggest an 8.5 grand swap of almost everything and charge me a hundred and ten quid for the inspection. I did get a free cup of coffee and the car washed though. 🙂 The thing is that transmission problems are very specialised and most official dealerships just concentrate on servicing work and carrying out part swaps under warranty rather than tricky repairs. If the car would be under warranty, absolutely get it diagnosed by a VW franchise garage who will be more than happy to make the cash from swapping out parts that they will charge VW.

I guess so, but wouldn't my local dealer get paid from VW anyway as this is a global campaign/recall for faults on theses gearboxes? Quote Link to comment Share on other sites More sharing options...
dougaberdeen Posted January 31 Report Share Posted January 31 I don’t know that I would bother with vw, your car has both a gearbox and ecu map so you have zero chance of getting anything from vw If a serious fault is suspected, they will run a full scan and reject it instantly because of the modifications as they will state that additional stress has been placed on the components i would find a dsg specialist and take it there Quote Link to comment Share on other sites More sharing options...
MJC1216 Posted January 31 Report Share Posted January 31 I would give a different view...there is no way you will get a goodwill from VW as you have modified the car BUT for £120 they will tell you exactly what is wrong. If you go somewhere else they may just start replacing the cheapest parts first until they get it right. Quote Link to comment Share on other sites More sharing options...
ssilversurfer Posted January 31 Author Report Share Posted January 31 Yes, i agree with you both. I have a few days to decide on the direction to take.😏 Quote Link to comment Share on other sites More sharing options...
Demise Posted January 31 Report Share Posted January 31 I’d take it to VW initially for them to diagnose, then you can weigh up your options.. Quote Link to comment Share on other sites More sharing options...
ssilversurfer Posted February 1 Author Report Share Posted February 1 Just a quick update: I am a little happier today I tentatively drove my car the 5 miles to the Transmission Specialist (Transmission Technology - Dorridge), and the owner (Ken) was a really pleasant and knowledge chap. His workshop was clean and there were numerous gears and boxes on the work bench. Ken plugged his VCDS and found the code 'P176E00 - Clutch 2 opens intermittently'. Ken assured me that the clutch operation was carried out by the computer (mechatronics) and this was the cause of all the issues. He would remove and send it to his man in Liverpool (whom he'd been using for 20years) where it would either be repaired, or replaced. A replacement unit is around £1400, however he said more likely it could be repaired at around £350. No other codes so hopefully this will resolve all of the issues. Ken explained that the DSG was merely a manual gearbox with a computer (mechatronics) operating the 2 clutches for seamless gear changes, and even got out the manual to describe the fault and set-up in pictures. Great guy, unfortunately he can't fit me in until the 10th Feb, but this shows he services are well sought after. I'll keep you all posted once the repairs to the mechatronics has been carried.

ssilversurfer Posted February 1 Author Report Share Posted February 1 Also, interestingly, when I search for the VCDS code P176E00, I see there is an Audi' Technical Service Bulletin' published for this very fault. The bulletin is used if a customer complains about harsh gear changes or gets 'gearbox malfunction' message. It also states that if the vehicle is out of warranty, then it is for 'information only'!

Demise Posted February 1 Report Share Posted February 1 Be Interesting to know what that service and damage code relates to from that bulletin I.E if the dealer would be effectively claiming for a new mechatronics unit from Audi Quote Link to comment Share on other sites More sharing options...

I would assume they would send a replacement mechatronics unit and have the the broken 1 back for a warranty claim (for labour) from the supplier. Expensive for someone!
