320d DPF Problems

Mancster · 07-05-2021, 05:27 AM

Morning all,

A friend of mine has just purchased a 320d and he's convinced it's suffering with DPF problems. There's a lot of hesitancy and it struggles under load, going up hill for example.

Has anyone ever tried any of the following DPF cleaners? They seem to get good reviews

Not saying it's not the DPF, but I'd explore other avenues before concluding it's that. What's the mileage? Has it been serviced recently, including fuel filter?

A lot of possibilities it could be : EGR valve, diesel filter, breather filter (often missed out if self-servicing or done at the cheapest possible price) ... or, of course, the DPF.

But the DPFs on these are usually good for 100k+ miles unless it's been used for a lot of short trips

Tell him to get a Vgate OBD adapter and BimmerLink.

He'll be able to see the DPF Regen status, and tell it to perform a regen on command.
That could be a lot cheaper than cleaning it unnecessarily.

Also for a further £20 or something like that he can then get BimmerCode and code things for his car too
