[PSA] DQ381 TSB (CID: 34K1)


Recommended Posts

I'm going to preface this post by saying I've not noticed any issues with my DQ381 gearbox at all.

 

Checking the Bahrain link with my VIN shows no link to any recall. Of course this doesn't mean mine isn't affected but their database isn't aware of it.

Am due a service/MOT in December so I will discuss any issues with the dealer prior to that time. If it is one of the affected vehicles, it may be a very interesting conversation indeed because of the TCU map it has.

 

If it does turn out that its affected and needs the software update, I may just have a chat with the mapper first to see if a deal can be done on putting it back to stock with a view to re-flashing later on. That's not an ideal scenario due to the required clamping pressure needed but that's favourable to having the gearbox destroy itself. In such a case I probably wouldn't drive it until fully resolved.

Lets assume reverting is possible or the dealer can simply overwrite, and the software update then goes on to flag the fault it was designed to detect, I would then assume because its a recall (being an acknowledged defective part in the gearbox) the factory would be obliged to authorise the dealer to fix it with the revised part. Then I'd look to map the TCU again but maybe wait and combine it with stage 2.

 

I'll reach out to the mapper anyway and get their advice on this recall in advance.

As soon as you modify the car you invalidate any right to any warranty. Your  car will flag as TD1 due to the number of times the TCU has been flashed.

Yes I've heard that mentioned, but it isn't always true and doesn't apply to everything, for example, a faulty head unit wouldn't prevent you claiming on warranty even if you were re-mapped. The answer here is it always depends on what it was you were claiming for. On the other hand, a warranty claim for a hole in the engine block where a rod had gone through it, would definitely be declined.

 

Regarding this particular update, I suppose it depends on whether the fault is classified as a safety recall, and in this case I can envisage it might, because it could be dangerous if the gearbox were to suffer catastrophic failure while you were doing 70mph on the motorway.

 

In any case this wouldn't be a warranty claim, it's a recall on something that can just as easy fail whether modified or not, which means the factory is obliged to fix it even outside of warranty, especially if its something that can make the vehicle unsafe.  The TCU update is just so they can add diagnostic checks to verify a fault. 

 

If the dealer were to advise me they'd be unwilling to touch it due to being modified, this is something I would have to take up with Volkswagen direct. If I do have to go through the process of sorting this I'll be sure to report back on here to advise the outcome, but I'm hoping I'm not affected by this at all.

I somewhat agree, however If it was a safety recall, VW would be required to write to all owners and recall the cars. This is simply an update.

Yes, VW often (misleadingly) use the term ‘recall’ for what are actually service campaigns / updates. Those service campaigns / updates aren’t safety recalls in the traditional sense and can usually wait until the next time an affected vehicle is next at the dealers (e.g. for servicing, repair or warranty work) to have the service campaign applied. I think a VW dealership should automatically check to see if there are any outstanding service campaigns on a vehicle as part of a normal oil change and oil change / inspection service, so using an independent specialist for servicing could mean a vehicle doesn’t get service campaigns / updates applied to it. 
 

As you’ve said, with a traditional safety recall, there’s a requirement for all owners of affected vehicles to be contacted with details of the issue and the procedure for getting it rectified. In the UK, that communication process to owners is coordinated by the Driver and Vehicle Standard Agency (DVSA) on behalf of the vehicle manufacturer. There’s a vehicle safety recall checking tool on the www.gov.uk website - link below.

Had mine (2017 7.5 estate) done on Friday at Parkway VW, Northampton. Have to say for a main dealership experience I was impressed, always a bit dubious about going to main dealers after some of the stories you hear/read about.

 

Nothing to report with regards to the update, still drives the same as before and no error messages so far. Will see how it goes over the next few days and if anything changes I'll reply on here, although I'm not really expecting anything to happen!
