PD150 ARL engine wiring voltage diagram

[mtN]

Hi, does anyone have wiring voltage diagram of ARL PD150 engine please ??? my car is in limp mode replaced turbo, n75, map fel temp sensor and is still in limp mode...
any help on this please

If you get it plugged in to VCDS it will tell you the fault.

If you get it plugged in to VCDS it will tell you the fault.

i did that changed turbo, n75, fuel temp sensor and still same roblems occur

You can't blindly change things and expect it to be fixed. It gets very expensive

Fault codes are a start - share them if you know what they are

Datalogging will help you to pinpoint the problem, as would a detailed description of the problem and what is happening - not just 'limpmode' without even a definition of what you think 'limpmode' is

What was your original fault code? What is your current fault code?

 

[mtN]

it was p0243 (waste gate solenoide valve A) malfunction, P0230 Fuel Pump Primary Circuit Malfunction, P0182 Fuel Temperature Sensor Circuit Low Input, P0401 Insufficient EGR Flow. Car has EGR deleted, i've changed fuet temp sensor and the same fault came as well as N75 valve as i had a spare one and garage told me that my vanes are stuck so they changed the turbo, but problem is still there, I left my car with electricians now to check any wiring issues.

I take it the fault codes have been cleared?
Has the EGR been mapped out or just blanked?

Yes, they been cleared and appeared again. I think it is just blanked.

The EGR needs to be mapped out otherwise the ECU will be looking for a flow from it. This maybe what is triggering limp mode.
Take the blank out and get the codes properly deleted again using VCDS, not the £10 generic OBD devices sold on e bay. VCDS will tell you a lot more than they ever will.
Good luck

EGR flow will not cause limp mode regardless, just a code and the EML on

Clearing fault codes is clearing fault codes, whether done with a £5 ebay special or a £270 VCDS cable

What you need to do next is use the live data facility on VCDS and check what your various sensors are reading/reporting. To me it sounds like a wiring issue or a faulty ECU.

Op do you mean a wiring diagram rather than a voltage diagram? as pretty much everything on the car is 12v aside from most sensor which have a 5v input

car is with electricians, but if its ECU can it be fixed ?

 

[Dan FR]

Cheaper to find a replacement and code it in I suspect. An auto-electrician is your best bet at the moment I suspect - keep us updated

 

[mtN]

maybe you know how much it is to code the ECU ?

 

[Dan FR]

Couldn't say. 10 minute job to code it in, need a VAG specialist / specialist tools to do it though.

I picked up the car today, so it was a broken wire to fuel temp sensor... Thanks to you guys who tried to help me out
