Just bought a 2009 superb 2.0tdi. Driving it home fault comes up showing a coil. Checked fault with OBD brings up p2111-Throttle Actuator Control System - Stuck Open. Read online that the first place to look is the throttle body. Does anyone have a guide to locate and clean the throttle body.

 

The car runs fine and didn't show any codes on the test drive. The seller is ignoring me.

Update:

 

So the seller agreed he will get his mechanic to take a look and cover costs. He found the fault and ordered the new throttle body valve. A couple of days later a dpf light comes up.  I told the mechanic about the new dpf light and he said its probably caused by the other fault. So I thought I'd wait for the part to arrive and carry on driving. So i'm driving and all of a sudden the car looses power and I crawl home.

 

The mechanic has taken the car away to inspect the car. 

 

I fear the worst for the car and believe Iv'e blown the turbo or worse the engine, either way it will be expensive and there's no warranty. After a week of owning this car it could be a write off. I just hope its just a blocked dpf and nothing else. 

 

The car would not regen, I tried for a hour on a long road for the required. This dpf thing is crap. I need to bypass it.  

The two faults are likely linked, the initial fault has probably prevented the DPF from performing a regeneration.

 

As you've continued to drive the car with a flashing glow plug light and a non-functioning DPF the DPF has filled with soot to a point the car has dropped into limp-home mode.

 

Now you are in limp-home mode it isn't possible to get the car to regenerate the DPF by itself, it now needs diagnostic intervention to perform what is called a 'forced regeneration'. If the DPF is too full then this won't be possible either. Stop driving the car if you haven't already.

 

Don't worry, it is unlikely the engine or turbo have been affected. How many miles has the car done? At 8 years old the DPF is already aging, if the car has covered above average mileage then it is possible the DPF has simply reached the end of its life.

 

You can buy aftermarket ones now for around half the cost of OEM (£1,000 including fitting). However you can also have the DPF gutted and mapped out (be warned that this could cause issues come MOT time and with a few people on here who take umbrage at removing air cleaning systems).

The car has done 48k miles, in Jersey that's high mileage probably equivalent to 90k UK miles as the are no motorways here and journeys only last 15 mins.

 

Haven't heard from the mechanic yet but I hope it's nothing to serious. 

Here in Jersey we don't have mot's or emissions tests. 

 

Could I not just remove the dpf and bypass it and remap the ecu?

You can (if you should is another matter...)

 

Can I ask why diesels are bought on Jersey if journey times are so short on average?

They'll never get up to temperature and it'll hammer the EGR and DPF being driven like that all the time

Diesel cars are very popular here. This is my first diesel car and I never heard of the dpf until the light came up.

 

I have seen company websites sell the bypass dpf part. Then you send them the ecu and they remap. Think I will look into this more.

In the UK - it's not yet illegal to do this but it is illegal to then drive it after the dpf has been cored and remapped

 

 

Not sure of the legal situation in Jersey though

There are lots of companies out there that will professionally remove the DPF for you. Be warned some are better than others so be sure to do your research.

 

There are generally two methods...

 

1) Remove the DPF and replace it with a straight-through pipe. Map out the sensors.

2) Remove the DPF, cut it open, remove the insides, weld it back up, refit it and map out the sensors.

 

The second option is preferred in the UK as during a visual inspection (i.e. during an MOT test) the DPF looks to be intact and it is therefore more difficult to prove it is no longer present / operational.

 

I'd be tempted to do some research on the legality of removing the DPF in Jersey, just to be sure so you have all bases covered.

 

As mentioned above, a 9 year old DPF covering only 5,300 miles per year has already had an extremely tough life. Even if a forced regen provides a brief reprise you can be pretty sure it'll happen again, probably sooner than you'd like.

 

Skoda do some fantastic petrol engines these days, the 1.2 and 1.4 TSI engines are extremely capable and DPF-free :-)

 

 

their petrol engines burn a lot of oil from what I've read on here

That's the 1.8, the later 1.2 and 1.4 engines are pretty robust.
