Car had the amber DPF filter light on the dash so i took it on the motorway to do a regen. Was driving just over 2000rpm in fifth for around 15 mins and then the glow plug light started flashing and then the MIL light came on and went in to limp mode (no power and very sluggish). I pulled over at the next junction and checked for codes using Torque Pro and it showed P2002, I cleared the MIL light hoping to get out of limp mode so i could do a regen but no joy.

 

Hoping its only going to be the G450 pressure sensor but not holding my breath.

 

Can anyone recommend a garage in the Sheffield area that`s reasonable who could fit the G450 pressure sensor and set adaptations for it. Does it have to be a VW specialist garage or is any reputable garage capable of doing this?

Hi there , did you manage to get your issue sorted ?

I'm having the same issue ATM .

 

No afraid not, still not fixed.

 

What i have found though is if i disconnect the dpf pressure sensor it gets full power + full boost back and is no longer in limp mode (but the mil light will illuminate). The car will not do a regen when in limp mode or if the mil light on.

 

Am just guessing, but to my limited knowlege i am thinking that either i have a faulty dpf pressure sensor (even though its throwing no code)  or the dpf is blocked.

I managed to do the same - disconnect the pressure sensor , car no longer in limp mode - but I tried to force a Regen on motorway j 29 to j 42 on M1 . Also removing the pressure sensor will giveaway another fault code p4073 or something similar . I have a booking for a service near Chesterfield in April and if I will get the situation sorted , I'll let you know what caused it . Cheers !

I will do the same if i get mine fixed before you and post on here what it was, good luck and hope you get it sorted.

Just found out they have moved premises to UNIT 5 WILLIAM HOUSE, DANNEMORA DRIVE, SHEFFIELD, S9 5DF.

@Radiogaga I'm assuming that you had a similar problem with your car . What was the outcome ? What was faulty ? 

 

Cheers !

Hi

No not a similar problem I was just telling joe10toes about the garage in Sheffield.

A quick update.

 

I put two lots of Wynns dpf cleaner in just under half a tank of diesel and drove it hard for a 100 miles with the pressure sensor disconnected (no change still in limp mode and dpf light on). 

 

This point i was kinda disheartened and left it for a few days, i decided to try again Friday and went for a spin. Disconnected the dpf pressure sensor and got the engine hot, pulled over reconnected the dpf pressure sensor and cleared all fault codes. Was driving in limp mode trying to get over 3000 rpm and the car just shuddered and got full power, flashing coil light and dpf light went out.

 

Took the car on the m1 drove 50 miles, i got home checked fault codes and showed bank 1 pressure blah de blah so cleared fault codes. Next day i took it for a 100 mile drive all motorway above 2000 rpm.....got home no fault codes  and seems to be running fine.
