Recommendations for new DPF, injectors and EGR cooler.

[BillyCool]

Hi Team,

My car had reached that point where it needs some TLC.

2.0 tdi FR ST 184 bhp CUPA engine code. 156,000 miles.

New DPF - it's knackered. Car regens every 30 miles and garage says it's toast.
New EGR cooler and valve (my choice to replace whilst DPF being done as they are prone to fail).
New injectors - #1 is over fuelling a lot and #3 isn't much better. Get lots of engine wobble at idle.

I'm invested in the car and plan to keep it, run it into the ground and bury it. I was expecting maybe a £5k bill for everything. However.

Quoted today:

DPF - genuine £3,345+VAT plus 6 hours labour
Cooler - £400+VAT and some labour but not much as the cooler is taken off anyway to get to the DPF.
Injectors - £1480+VAT plus fitting

Total is about £8k. Much more than I expected.

DPF price is massive. Garage said it's a dealer part and fully warrantied. They have just sourced an OEM one that they are happy to fit and that is £1100+VAT, more in line with my expectations.

I'm going to delay the injectors until DPF is done.

Are there any good OEM brands for DPF's? Autodoc has a few but I have no idea what's good. I just want to understand the price differences.

Also injectors. Any ideas whether it's worth trying to save a few £ or go with the fully branded/warrantied ones.

Thanks.

Ouch - my 150,000+ mile CUPA is regening around 70 miles so i'm also looking at DPF options!
Luckily our DPF is able to be split (later versions are welded!) - 04L131606EX it's actually a combined DPF & CAT - which is one of the reasons the OEM part is so expensive. There are aftermarket companies selling just the DPF part - and large band clamp.

For example:

Which is using the more expensive silicon carbide.

I have also been musing if I can clean my existing DPF - it's just such a pain to get to:

Regarding egr cooler.
04L131512D

was replaced circa 2016 by
04L131512BQ

Which went from rectangle holes - to round. These egr coolers are subject to large thermal stresses - and would think the round version copes with this better? Personally I would only change this if it was leaking.

Regarding your injectors - have you tried diesel fuel system cleaners/additives?
OEM number 04L 130 277 AE = Bosch 0 445 110 470
Also I would inspect your dogbone mount.

My next job is changing my cylinder head cover as it has a slight mist around the back edge - and I think it is letting too much oil through as I can see oil traces into the turbo. - which might be contributing to my oil consumption?
And I'll also be changing my air to water intercooler as have noticed a leak (another common problem!)

Should be able to remove the DPF and have it properly cleaned on a machine, regain 90% of original capacity.

They all need it eventually, on-car cleaning is ok but only works to a point.

This is how a properly knackered DPF looks on a cleaning machine.
