I have a 2006 Passat B6

170 bhp BMR engine code

It has 223,000 miles on the clock

For the last 5 years I have been running it on a diesel/waste veg oil mix, approx. 80,000 miles in that time.
Service the car, change oil approx. every 6000 miles.

Summer mix 50/50 diesel/veg oil
Winter 90/10

Loads of engine lights came on last Saturday.

CEL, flashing coil, DPF. Limp mode limited to 3000 rpm

Read the codes with dongle VAG COM, though bought on ebay 10 years ago so not licensed.

The DPF was replaced last year with a new one and has only done 15,000 miles or so.

So, replaced all glow plugs as they were the original ones when the car was new. Replaced with NGK's

Took off anti-shudder valve and cleaned.
Took off EGR and cleaned. Checked the mechanism which works fine.
Changed the exhaust pressure sensor G450 and re-set with VAG COM.

Only codes now are the DPF particle trap below efficiency. Can't get out of limp mode.
Have tried to force a regen on the move (wife loves me!) but the DPF won't regen.
Have never done a stationary regen but would it work?

Any suggestions?

I think I should go to a VW specialist to get this done.
Any recommendations in the Sheffield area?
I know Crasher is in Nottingham and have gone to him before but I don't really fancy going on the motorway in limp mode , 20 mph up a gradient!
