Re: Golf Mk V 2L Tdi BKD engine misfire at idle

Hi, That is common for all 2.0 tdi engines and it is usually more noticeable when the engine is at operating temperature. I found that two things can cause that. First is injector seat inside the cylinder head. Over time it wears and blow by gases deteriorate radial tip of the injector and it is not...

Re: Transporter T5 1.9 TDI AXC

The way it works on VW is that you have requested value and actual value. You can see it in VCDS mvb 011. ECU is requesting some calculated value and then it monitors turbo pressure response over MAP sensor. both values shoud be within 100 mbar of each other. If it went over requested for than it wo...

Re: Transporter T5 1.9 TDI AXC

If I'm reading this right rpm 3444, Maf 855, and boost 1887, than I think it is the cat. Your MAf maxed out at over 1000 at one moment so that is ok. But 1877 of boost at 3444 rpm is low. at that speed it would be 2000-2015 mbar at least. the simplest way of confirming cat is to release the bolts fo...

Re: Transporter T5 1.9 TDI AXC

I wanted to ask about that one but I forgot :D . That sound can mean two things. Bad cat or cracked hose. If there is a lot of smoke on the tailpipe when you put your foot down than it looks like boost leak. Otherwise it could be the cat.

Re: Transporter T5 1.9 TDI AXC

Hi, you are welcome. I'm glad to help if I can. Carbon build up can be one of causes of lack of power since it is restricting intake ports so engine cant breath. If you have negative readings than ECU is taking fuel away because those pistons are moving faster, and positive value means that is addin...

Re: Transporter T5 1.9 TDI AXC

Hi, from what I saw in your scope data injectors seem to be ok. You would get better readings using VCDS mvb 013. On idle rough running values below 1 are considered ideal. Also you can see maf in mvb 003. It is measured under load in 3 gear on 3000 rpm everything from 800 mg/str is super. And you c...

Re: Another win with Pico!

I use PP939 kit. It works for me, but I think if you use Sykes than you can use TA 250 adaptor kit B with WPS

Re: Another win with Pico!

Thnx Dcunnin35, Yes, you are right. It saves a lot of time and guesswork which is the whole point I think and that it is not that hard to interpret as long as you use logic. It allows you to see the malfunction ( that is how I see It :D ) @STC, I found that small percentage of tech's want to use thi...

Hi, Those readings are way too low. Compression pressure bar When new 25.0 … 31.0 Wear limit 19.0 Maximum difference between cylinders 5.0 If you need any specific data from ELSA I can send them to you
