Its regarding the Yeti that I have just repaired but a general question for any model.

 

I bought it as accident damaged with airbags deployed so was not concerned that the engine would not rev beyond 2.5k rpm, after doing the repairs and clearing down all the fault codes it will still not rev above 2.5k and initially emitted a very sickly smell of death which cleared when up to temperature.

 

I did a VCDS scan and despite pressing save and even the button to show where the file was saved its not on my computer so in true Blue Peter fashion, here is one I did earliere before the repairs, to make it easier I have deleted all the no fault found guff and have highlighted the fault codes that remain which to me are the only ones that might cause limp mode, the light bulbs are yet to be replaced and the aircon awaiting pressurisation.

 

The front of the car is still on axle stands so I have not driven it, the steering angle sensor may well go out after driving a few yards as I had to remove and refit the clockspring assembly.

 

It only leave the TPMS module, it does not have the pressure transmitters so is the ABS sensor system, it has a reset button which does not seem to do anything, should a failure of this flaky unreliable system really put the vehicle in limp mode? Does it need to be driven to reset?

 

Scratching at straws but being a 4wd Yeti could it be that its at an angle with the front wheels off the ground? I deliberately did not put it in gear with the engine running.

 

Surely anything that would cause limp mode should show a fault code, there are still a couple of dashboard lights showing, the ABS/traction control one and another that looks like a light bulb.

 

It doesn't help that the car remains in the UK and I am now back in France and the post repair VCDS scan has not saved to the computer.

 

Thanks for reading, any suggestions?

Title correction

OK, I have found the missing autoscan, it was saved elsewhere as a log probably because even after using VCDS all this time its not obvious to me how to do and record an autoscan.

 

Here it is but its only the top level and doesnt show the detailed faultcodes, pretty sure they are unchanged from before and concern mainly the ABS controller and steering assist.

 

Would either of these cause the engine to run in limp mode?

 

If they dont then in the absence of any other fault codes my engine is not in forced limp mode but what would cause it not to rev above 2.5k without generating a fault code?

 

to my mind a blocked DPF would create an insufficient flow or pressure drop code.

 

Non operating turbo would create a boost pressure outside predicted parameters code.

 

what else could it be?

 

The key might be that its been standing for maybe 6 months, I had a Galaxy that was performing fine in everyday use but after going to OZ for a month it ran like a dog and blew an emissions pipe from the exhaust, the catastrophic convertor had become blocked.

 

I looked through loads of measuring blocks in the engine control, its scary just how many they are, from memory it showed ash at less than 5% and mileage since last regeneration equal to the total mileage (85K) on the odometer which struck me as strange.

 

Any help will be gratefully recieved as this really is the worst case scenario for me, an engine that wont rev and no fault codes unless the 2 below could cause limp mode

If your trying  to rev engine whilst not moving it won’t go over 2.5k.

I'm not sure if I am allowed to say this but I think I love you

 

I was pondering this last night and also whether it could be that the bonnet was open, I dismissed them both as how could they do the engine max rev test during the MOT and how could you get a good launch off the line at traffic lights.

 

I am now in another country to the car so cannot go and check, to give me peace of mind and allow me to sleep at night until I return to the vehicle could somebody else kindly confirm the above and also explain how its overcome in the MOT test and doing fast takeoffs please?

 

In the meantime maybe Google will provide the answers.

 

Thankyou so much for your response Kenny!

As usual Google led me back here:

 

I did not think to depress the clutch although you have to do that to start the engine (which I hate with a vengeance) and would not put it in gear as its a 4x4 and the front was up on axle stands with the rear wheels on the ground.

 

Editted, I found several other references to modern VAG TDi's having a rev limit in neutral so I can sleep at night again.

 

Seemingly it can be over-ridden by depressing and releasing the clutch or switching off all the 3 letter acronyms

 

As was stated on pretty much all the other threads, - you learn something every day!

Been over a month before I could return to the vehicle in the UK, its still up on stands and the engine will still not rev beyond 2.5K with the clutch depressed in or out of gear.

 

Does it actually have to be moving?

 

Weather permitting it may be another week before I can get it back on its wheels and driving to try it in motion, if it could be confirmed it would stop me worrying for nothing.

 

My neighbour has an Octavia with the same engine, I will be able to check his when he returns next week.

 

How do the MOT testers get the engine to rev for the smoke test etc?

Short answer I think is yes. There are probably many technical reasons but my guess would be that the rear wheels are static. I'm sure when you get it on its feet you'll find all is good. 

Personally I wouldn't try putting it in gear with just the front in the air. If the haldex engages you'll be in a world of pain.

Having googled again it seems the vehicle has to be in motion, I had tried it in gear with the clutch depressed but did not for obvious reasons lift the clutch.

 

disabling the TCS should allow it to rev, just tried it but the wrning light is on anyway together with lots of others, I think just driving it for a few meters will sort everything out, hope the rain stops soon so I can try.

Tried my neighbours 2.0 TDi Octavia, revs limited in neutral or in gear with clutch depressed, he parks on a hill and in neutral with the the throttle to the floor but the engine revs limited if I let it roll back half a wheel revolution it revs up.

 

So I can sleep better at night.

 

Looking forward to getting it on its wheels for a test drive which with luck will put out the other warning lights as well.

Drove it for 7 miles today, all warning lights out and fault code city is now a thing of the past

 

Much more nippy than I was expecting but wont be able to give it the beans until the brake pads have cut through all the built up corrosion which will take a long time, the discs are looking a lot better than I thought they would be, doesn't seem to be the grooving pitting or flaking that I was expecting.

 

Just need to regas the aircon & there will be zero fault codes, never got anywhere near that state in my Octavia.
