If it’s a 2.4 have the EGR mapped out and fit a genuine Mann Hummel ProVent 200 oil catch can.
If you have a 2.2 then then you can’t map the EGR out without mapping out and removing the DPF and replacing with a “Faux DPF” and hope thats not noticed at your subsequent MoTs. Else you can change oil every 5k miles, run a bottle of Forte injector cleaner through the engine ( ideally via filling Fuel filter) once every oil change and use millers ecomax each time you fill with diesel. Noting if I had a 2.4 I would map out EGR and fit a ProVent. For my 2.2 I change engine oil and filter at 5k miles or once a year, whichever comes first.I also change the air filter and fuel filter at the same time. I run a bottle of Forte injector cleaner via the new filter at the same time and use millers ecomax each time I fill with diesel. As it’s a 2.2 with a DPF the glow plugs are not just used for cold starting, they are used a fair bit while the engine is running ( no Glowpug light illumination). So ensuring you have a decent diagnostic tool such as a Nanocom or GAP IDTool to test and highlight glowpug DTC’s is beneficial . And if faults are detected then don’t leave it, change the glowplugs for new quality ones I.e Bosch ASAP When I recently changed my glow plugs I noticed the inlet manifold was clean with minor carbon. My Map sensor was also very clean, so either my driving pattern ( no short journeys) or / and my engine care measures seem to be working. Last edited by Ianh on 25th Feb 2025 1:21pm.

If I'm not mistaken, these carbon clean products are all introduced via the fuel system. So on a DI diesel like ours, at best all they'll do is clean the injectors and cylinders. I can't see how it'll have any effect on the carbon build-up in the intake and inlet manifold which is the problem area. Also, I struggle to see how these chemicals would survive the combustion process and somehow clean the EGR. 2007 110 TDCi Station Wagon XS

I agree Bluest, i don’t think the additives will clean the EGR or inlet manifold, what I do think they do is keep the engine running as efficiently and clean as it can and therefore reduces the amount of carbon that reaches the EGR and inlet manifold. My glow plugs had minimal carbon on them as well, which is a godsend for removal. I expect the additives helped this.

Or fit a blanking plate with a hole, between the exhaust manifold and egr cooler. I cannot remember the minimum hole size though. Puma 110" SW

^^^^ Inlet manifold + sensors are also very clean on my 2.2 No additional clean mesures - only oïl + filter changes as scheduled It's the same driving pattern, which keeps the engine clean  |
