so he bought another one?

[Hell Razor5543]

Yep, a C5 110HDi, and I think he likes it. It is just that he wants something with more oomph!

Hester flaps are a big known issue on them so be ready for getting the dash out of they go as only some are easily accessible for a bodge repair with it in situ.

The hdi90 is gutless, and more to tax as well so best avoided.
Some alloys are centreless so watch for that, hydraulic pumps are a known issue that can be working fine for ages and then just go pop, spheres last a lot longer than on the older cars but they can be a burger to replace and can involve replacing the cylinder as well. I know this all to well!
Door handles can snap as well which can be a pain.

I'd avoid the 16v units all together as they have dpf. More to go wrong and they are not cheap to sort, common to fail when the fuel cap sensor fails and they start clogging up and then there is the fluid in the system as well... Nah, I've been bitten by a 1.6, 2.2 and 2.0 16v engines. I'll not touch them if I can avoid it as it's too much faff!

[taffy]

that was very interesting ..so what u running now? 8v?

[KP]

A 2.5td xm!
My folks have a 2.0 16v HDi but dad isn't happy with it as a long term car and has even thought about petrol with lpg they are that bad.. Just look online, egr, injectors, dpf... Even seen issues around the vanes in the turbo but then that can be fixed without too much fuss but do you really want to spend the time with it?

Unless it's an old school diesel I think diesel is going to start dying down as the increase in mpg is outweighed by service costs, repairs, and higher fuel price..

[taffy]

good man hahaa!!
yea i love hdi but xud for me is reliable less electics and dmf!!

Clogging is ALL down to the type of driving! And noggins that dont know how to check the Eolys fluid levels!!

If you do a lot of town stop start driving then expect issues!!! However, if you do lots of motorway/dual carrage way driving at 70mph then you be fine.

1.6 Design HDi 16v engines DO NOT have DPF or Eolys, but are the only engine not to have it. Will I think you have been put off by 2.2s, however, the 2.0 16v engine is a vast improvment over the 2.0.. there appears to be far less for spares/repair compared to the 2.2, and PSA changed the head design for getting rocker covers and injectors out!

If you know the correct procedure for treating the 2.0 16v with regular oil changes and frequent motorway drives then go for it!!

I think people buy Diesels, but use them for too many short journeys and therefore they dont get a good blow out to keep them clean!

I agree with Will though, that old school DERVs are STILL tougher and better, the last of the best Diesels being PSA 8v HDi 110 2.0 engine...

I know your dad has one Will, but thats one out of how many? My mum and dad have a 2.0 16v HDi but do far so good!

[taffy]

ive tunned my lucas and kkk within an inch of its life for the last 10 k and still get close to 50 mpg

[daviemck2006]

I have absolutely no issues with my 2.0 16v hdi engine or dmf or dpf. I have had a rear radius arm bearing and I have a stuck temperature flap on drivers side that I will have to do something with very shortly cos it's blooming freezing here now. I also had no issues with dpf on my earlier 2.2 hdi. It must be because I do very little or nil city driving and it gets a 220 mile each way run once every 6 to 8 weeks to my sisters.

[citroenxm]

DavieMck., as you say. Motorway driving is the Key !!!

[daviemck2006]

I've to go 50 miles to get a dual carriageway and 120 to find a motorway lol. Most of my mileage is single carriageway but often 20 or 40 miles at a time. I'm doing about 900 miles a month and that's no commuting

Clogging is NOT all down to the type of driving

The 2.2HDi was one of the most reliable out of the lot! Mainly because it had no DPF, it had been deleted, The egr had been blanked, and the DMF had been replaced as well...

A DPF can clog from the simple filler sensor failing. This will only become apparent when it tries to run the regen cycle and fails. At which point the filter is already getting upto a decent soot level and unless the issue is sorted soon the gets worse. And lets face it, not many people with them will get it sorted soonish. Also i've had a C5 1.6 HDi Design WITH DPF so the batch your on about is very small indeed. Most came with DPF

My folks current 16v HDi has put them off it enough as even though its been serviced on the dot its 160k miles history, the service intervals are just too long for the oil. Having spent some time at the local dealership parts dept they have confirmed that the issues they have with the engine are quite common. If they make it to 200k without injectors, dpf or dmf needing doing then its a very rare car indeed!
My dad does lots of mixed driving, one day it can be a trip of upto 15miles each way, the next day it can be down to cardiff or london and doing 20k miles per year certainly gets the short trips discounted

The issues with 16v in HDi's are showing through though as now the 1.6 has gone to 8v and i wonder how long it will be before the 2.0 engine does the same...

[citroenxm]

check again Mr M! 1.616v DESIGN models DID NOT GET DPF!!! Its the only model that didnt! So you might not have had a Design model!!!

All other 1.6 16v models did get DPF, thats LX, VSX and VTR etc etc

[KP]

Mr H will confirm what I had on my drive was a 1.6 hdi Design model with DPF

[citroenxm]

Well it wasnt a design then! Design spec didnt have DPF!!
