Take this with a large pinch of salt, but the VAG specialist who did the valve replacement said these engines can run in a high or low pressure mode, which is what the valve controls. They said that the oil flow will still be fine as other sensors will throw warnings before anything happens so can be a bit of a false positive.

Hi Adan, So it appears P06DA00 was never the actual issue as the limp mode reoccurred after the engine oil pressure valve was replaced. The only reason we stuck with it is that it was the only error code that persisted after being wiped. The garage that replaced said it seemed to be in reasonable condition anyways. The actual fault was likely either the camshaft or crankshaft speed sensors, though I only had the car for a relatively brief period (<1k mi) after the repair so it's difficult to say if that was the fix. For me, the symptoms were: Going into limp mode and losing all driver assistance systems (TPS, ACC, sensors) which may or may not clear on a restart of the engine Stalling even when going at a steady speed in a straight line Gears jumping severely between 2nd/3rd/4th, almost like it would attempt the shift and fail resulting in some violent juddering I would check whether you possibly have P072600 and P032200 present as well as these seem to be much more common. Best of luck!

Hello all, I'm looking at picking up a 68 L&K 2.0 TDI 190 4x4 estate with 85k miles and had needed some advice. It appears in the service history that the Haldex has never been touched. I talked with a local garage who suggested this shouldn't be too much of an issue, just that the filter will need cleaning out and new oil. Is this realistic or is there a good chance it may need a complete unit in the near future if it's never been touched? I'm fairly confident it's working on the test drive, as some spirited take-offs that would've resulted in wheelspin in the FWD 150PS version I used to have were drama free. Additionally, I plugged in my OBD scanner while on the drive, and there are quite a few error codes present relating to low voltage on some of the comfort/accessory systems.

The car has been sat with the dealer for at least 6 months, so is this likely to be down to being sat for so long? Is there anything else I should possibly look at? Lastly, the first owner seems to have been somewhere in NW Scotland with some coastal air, so there is some corrosion like on the bonnet latches, a small patch on the boot and various other spots in the engine bay: From what I can see of the chassis and suspension components, these all look like reasonable surface rust, but are there any other parts that are particularly prone or vulnerable to corrosion? Thanks in advance.

To give a final update for anyone else looking at this issue, at the end of Dec, a local VAG specialist agreed with the P06DA00 error code being a possible cause. They checked the battery health and was fine. The seller agreed to cover the cost of a new engine oil pressure valve and the local garage carried out the work. That seemed to work for around a month until the end of Jan, when it again went into limp mode. Turning the car on and off would sometimes clear the code but not consistently. I also experienced the gearbox juddering while shifting between 2nd-3rd and 3rd-4th, as well as it outright stalling while coasting at 30mph. After more back and forth with the seller and the local Skoda main dealer, debating whether they had exercised their right to repair or not, we determined it was likely the camshaft or crankshaft speed sensor, which the camshaft sensor fault present in the original diagnostics as P072600 and P032200. The seller eventually agreed to collect the car and they replaced the crankshaft speed sensor, assuring me it was definitely this and not the camshaft. I had the car back after about 2 weeks. Test driving it, the issue seemed to be resolved, with lots of odd driving on steep hills etc to try and get any of the previous symptoms resolved. And then 4 days after having it back, while reversing onto my drive, the steering wheel goes click and the dash throws a driver's airbag error and all the steering controls are non-functional. I say enough is enough at this point and luckily they agree to have the car back in exchange for a refund. We did have a quibble over the fair usage deduction, with him trying to charge 45p/mile. I pointed out all the hassle we'd been through, that a chunk of the mileage was them collecting/returning the car, and that trading standards had a recommended framework (which you can see here) which should've been around 17p/mile. We eventually compromised on 26p/mile and after 5 weeks (not the 2 promised) I get the money back. In hindsight, I think my risk appetite was a lot less than I thought. But luckily enough a L&K 190 has just popped up for sale 5 miles away so fingers crossed!

Ended up at 12.6 after a 5mi journey so I guess I can probably strike that out. Initial chat today with the seller went down the line of "oh well a battery costs us £60 so that's what we'd contribute", never mind that the Skoda quote for an OEM spec one is £400, a few independents have said ~ £180.

Measured the battery this morning and showed 12.25 V, so I guess that's the first suspect to deal with right?

Hi all, 2 weeks ago, I picked up a new to me 67 plate SE L Executive 2.0 TDI 150bhp from a private dealer. 95k miles on the clock but seemed in good condition, full Skoda service history etc. and a good price. It was a 8h round trip, but seemed to be worth it... I've done 500 miles since with no issues, and then this morning as my partner was commuting in with, takes it over the medium-sized hill (10% gradient), and while slowing down the other side, it throws itself into limp mode and the dash lights up: Glow plugs ESC TPM Warning that "Electronic parking brake not available" Doesn't go over a certain RPM and will only just get to 40 mph. Gets to work ok, has to park without parking assist as that's now broken, turns it off/on and all the faults seem to have gone. I head over to swap cars with her, and take it to the garage next to her work as no one else has availability. They've done a diagnostics with dozens of faults showing, all of which cleared except for P06DA00 (but nothing on the dash), advised it would likely need more investigation but should be okay to drive home. They've also noticed the battery is "not clamped down", though other than a cover I'm a bit unsure what's missing. They didn't have any space to look at it until the new year as well. I drove it the 15 miles home, including back over the same hill with no issues, car feels perfectly responsive as it has been (and with other Superbs we'd tried). I spoke with the local VAG service centre, have it booked in next week but they couldn't advise anything else until they'd seen it. I had approached discuss "distance purchasing" with the seller, and they agreed they would cover "reasonable" costs to have it fixed locally in case something went wrong, haven't spoke to them yet as want to go with a strong case. So I guess here are my questions: Should I even entertain a repair or should I just go down the refund route? As well as it being within the 30 days for right to reject, part was paid by credit card so I'm happy we'd get money back minus some mileage etc. I've not found much on this specific code on this forum, though others have had similar symptoms, all of which seem to have varied from ABS sensors to units, or engine oil pressure sensors to whole Mechatronics. Is this a can of worms that's not worth touching? Not only is everyone else booked up, but I'd prefer an official service centre to look at it. Am I being reasonable to expect this to be covered? I'm not sure the garage could tell which codes were fresh and which were historic (or didn't make a note at least). Should I be getting an OBD reader so I can keep an eye on these myself? Thanks in advance
