Add me to the list. CXEB Engine changed 80% by VW June 2024, now having intermittent coil light issues. Been into VW about 6 times and now with now conclusion. Just want them to change the Turbo now.

Odd they didn’t replace the turbochargers at the same time?!
They obviously run on the same oil and the turbochargers are highly susceptible to contaminated oil.
Perhaps because they were footing 80% of the bill.
My18 204 just done 52000 Full service history…..I’ve had coil lights and EML lights on over the last 18 months…all relating to Boost issues ..recovered many times to VW but as they couldn’t replicate the fault no major parts changed N75 was replaced but still played up …it may be a coincidence but all faults have happened on hot days and a hot engine…so i do all the good things like allowing the engine to run down after long runs ( oil temp returns to normal and allow turbo to spool down ) I currently use 0-30 as used on last VW service and it consumes 250ml per 1000miles which is acceptable….but I tow so now considering having a oil cooler fitted due high oil temps…I’m convinced that there is some link to engine issues with poor thermal control hence I’m getting the water cooling system checked and changed and oil changes more often….
I love this van it’s power delivery is fantastic but I think just following a service plan is not enough….we all know our vans better than the dealer does..
Let’s face it the original Bus was a petrol vehicle and has today a cult following …and not a diesel which has created many issue to stay clean..it’s just we need to understand our engines and keep them happy…not all 204’s are bad

VW service plan is devised to enable a commercial vehicle to survive to the end of the 5 year depreciation cycle with minimal service costs and fleet downtime.
Update to above: my mechanic friend now started turbo removal process (which isn't easy!). Removed small turbo last night and shaft had snapped completely, and exhaust inlet turbine badly bent. So the intermittent rattle noise was this bit rattling around. Will try and remove big turbo tomorrow, and then either send them in for repair if repairable, or buy new ones. If buy new think the turbo?/manifold?/egr pipes? changed slightly (my van CXEB from 2016) so need to be prepared for that. If anyone knows about this please let me knowAnother possible 2016 CXEB diesel 204bhp engine/turbo problem.
Van made weird air noise from engine and went into limp mode. When I tried to accelerate coil light started to flash. Struggled to get home. Turn off/on, not sort it. Then noticed intermittent rattle from engine. Obd11 code P029900 turbo underboost and noticed older fault 2k miles ago P046C00 EGR sensor A circuit range.
Pendle engine and dsg map been on since Feb 2023, with 270bhp. Van now on 40k miles. Regularly serviced, driven conservatively ish, and been amazing up until now.
A mechanic friend has checked turbo's. They seem ok, bit of sidewards play on small turbo which might be the issue. Bit of oil in pipes, and some fine alloy shavings in pipes and intercooler/charge cooler.
Thinking of sending turbo's in for rebuild. But wishful thinking it might be intercooler/charge cooler. (And reading all the CXEB failure messages it might also be a whole host of other things)
Mechanic mate coming over again for further diagnosis.
If anyone has had any similar symptoms please let me know.
Also read that you need to increase oil pressure to new turbos whilst running in?

Remove the map, reference my previous post #380.

Add me to the list of engine failures 2018 204. EGR blocked at 44000 miles, replaced and blocked again by 54000. Oil consumption creeping up from 1 litre in 10000 miles to 1 litre in 5000miles. EGR blocked again by 66000 miles. Compression test showed 24b 19, 18 and 14b.
New engine, turbos dmf and cat refurbed. DMF found to be shot also replaced. T32 camper conversion, serviced every 10-12000miles as per the book. Lots of motorway miles loaded with camping gear.
I guess emission control systems destroy engines. Will reduce oil change intervals going forward.
Van is so much smoother now, didn’t notice the deterioration as it was over 7 years, fuel consumption much improved also.

Add me to the list now too.
2018 204 4motion. 103,000 miles . Owned since new and cherished, regular oil changes etc. Consuming oil at an alarming rate and dpf regen every 30 miles or so. I looked around at new vans and I just don't see the value in them , my T6 has all the options and owes me nothing so I've decided to keep it and get the full works done by Darkside. Booked for their earliest slot in December. I will take out shares with Millers oils to keep it fed until then

Have they recommended replacing the DPF and turbos too?
Your van doing a regen every 30 miles indicates a very blocked DPF which will knacker your small turbo shaft very quickly, so be careful with that if you intend to reuse those on the new engine.
Exactly what I was thinking.
If you have a choice stop driving it, If you can’t then change the oil filter to prevent it going into by-pass and preferable do a hot oil change.
So I had a mobile dpf cleaner come and see me two days ago . The flow rate through the dpf was good , as was the ash and soot levels. It didn't warrant a clean so he only charged me for diagnostic. My oil analysis is showing a high soot and iron content.
I won't be fitting a new engine without new turbos and everything else that goes with it. I'm also getting rid of all the devil's emission crap with an egr delete, adblue delete and dpf gutting . Basically future proof the van .

DS exchange the turbo units I guess so surely a totally wrecked turbocharger is worth less than something that can be reconditioned?
I’ve recently been watching some DieselPumpUK videos on YouTube and if I were replacing a Transporter engine I’d want to find out if an OM606 engine would fit (appreciate it would need a lot of work).
Their builds seem to run very clean without all the emissions guff that manufacturers design badly and just whack on a normal engine hoping for the best.
More mechanical and less electric bits too with the DieselPump engines, and some serious power.
Hopefully I never need a new engine and my little 102hp unit just keeps plodding away

Just to be clear I am nowhere near the amount of oil use VW deem to be excessive. I have noticed an increase and the wear metals in my oil are also a sign I have this issue. The dpf regens could be caused by any number of reasons , only doing very short journeys at the moment for instance. I'm not waiting for the van to explode or stop before I do anything about it hence me booking in with Darkside. Another oil analysis will tell us what's going on ie if there is an increase in iron levels. There is no way I will just replace the block and leave all the 100,000 mile old ancillaries and turbos on it. Renew the lot and start with a fresh slate is my view on this. If it does become problematic I have other vehicles at my disposal.
Apart from servicing the van has cost me very little over the 7 or so years I've owned it so I'll just take it on the chin and move on

So update from me....
Turbo replaced by Retro Resus and have since done 1700 miles. While it appeared the van wasn't using oil for a while, oil lights come on inidicting it's used about 1ltr in that time. Back on the phone to RR in the morning I guess.....
