Customer Question
The injector light is...

The injector light is on, the turbo is spooling but it is in limp mode, had an engine clean at the weekend and he said it is all working fine but there is a lot of back pressure so he thinks def needs cleaning, could not find any fault codes so not sure

Mechanic's Assistant: Do you have a scan tool to read the codes?

Yes there is not any faults codes present

Mechanic's Assistant: What year is your Turbo?

2006 suzuki grand vitara ddsi

Mechanic's Assistant: Are you fixing your Turbo yourself? What have you tried so far?

I have tried an engine clean and purchased a new def pressure sensor but am currently looking at getting the def cleaned

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

It has been in the garage and they quoted me £5000 to fix it, they said it needed new dpf filter, egr valve, throttle body and new injectors, the carbon cleaning company could not find anything wrong with the engine and no fault codes but said there was a lot of back pressure to the engine

Hi..there..

If the engine is running fine..why has your garage quoted for a new EGR , Injectors , Throttle body? Did you ask them why those needed to be renewed provided the cars runs generally ok?

You mention the injection light being on..so has anyone scanned for fault codes? if so what are they...

How many miles is on the car?
