Turbo lag when full acceleration

Talk about general things related to the new VW Scirocco in here.

Turbo lag when full acceleration

Postby yellowplum » Thu Apr 11, 2019 6:07 am

I've noticed very recently on the last week that if I put my foot to the floor you get a mild push pull type acceleration. It doesn't affect the acceleration in the sense that it prevents it from accelerating but just noticeable that there is a lag, as if it is trying to accelerate, then pull back then lets go (but this happens very fast) and then disappears once it goes over an amount of revs.

I had this type of symptom recently. I still do not know what it was or the cause, but i removed the coil packs and spark plugs (which werent tight strangely) to check them. When i re-fitted them the problem went away. Perhaps try that to start. (If petrol engine of course).

It could be lots of things. Ideally get it looked at by vagcom or vcds (computer plug in to obd2 port). Or somewhere that can do good diagnosis.

It's not, it's diesel, I know the plugs have never been replaced on the engine, but I wonder if it is the start of a coked up turbo. I have VCDS, will plug it in next week when I get a chance and read it.

Diesels don't have spark plugs...

With regards to your issue, if no relevant fault codes are stored then you want to do some live data logging using VCDS when the issue occurs to identify the source as it really could be any number of things.

I know :nod: - although something strange has occurred this last week or so, if I start the car and just sit in it while it idles the rev counter increases slightly and the engine management light comes on. The old windows laptop I used with VCDS is on charge, hopefully I will get a chance in the next day or so to plug it in and take a look.

I was thinking to replace the glow plugs (it has done 120k miles) and they have never been replaced.

I just don't want to get rid of it as I like it too much :) Although have ordered a new car to arrive in July.

As you probably know the glow plugs are only used for a short period of time during cold starts and unless you're having difficulty getting it started on cold mornings, changing them will have no real benefit.

If the EML has come on even intermittently then the fault that triggered it should be recorded.

Those 3 engine fault codes look very old (2013). Try resetting the counters to see if they reappear.

It did once I arrived in Cardiff today it’s non stop with the engine light and the constant engine four once I turn the car off and on the engine fault disappears from flashing but the management light doesn’t. It goes into limp mode until you turn off and in again, I’ll rescan when I get back in Friday.

RAC came out to clear the faults as they seemed to get worse, he found three from when I cleared them. (still stuck in Cardiff until tomorrow). The actuator is the main problem he said, but also there is an electronic fault with the auxiliary water pump, the pedal still is an issue but that might be the sensor rather than the pedal itself.
