Buying advice on C5 X7

Post by mattsterzz »

Hi there,

I'm currently looking at buying a C5 and currently cross shopping two versions. They are both Exclusive models, one is a 2010 3.0HDI and the other a 2012 2.0HDI.

Just wondering if anyone has any advice regarding the 3.0? I've done some research that suggests they aren't the best engines reliability wise however there are suggestions the faults primarily lies with the ones in Land Rover's. I'm currently swaying towards the 3.0 as I'd prefer the additional power.

Also wondering what the reliability of the hydropneumatic suspension is. Living in New Zealand, C5's are rare. I'm not too concern about reliability, its a price to pay to have an interesting car, but as I learnt from my previous Alfa that you can wait for months for parts and the rarity of the suspension set up (whilst very appealing) does concern me.

Overall I'm very keen on getting myself a C5, but any advice regarding the 3.0 (or the 2.0 for that matter) as well as the suspension would be appreciated.

Thanks,
Matt.

Hi Matt. I think you mean 'Exclusive' trim level, there aren't any 'Executives' in the C5 ranges :-D

As for suspension - bear in mind you are talking about 2 very different setups between a 2.0 HDi 4 Cylinder engine and the 3.0 V6 HDi engine as far as suspension goes.

The V6 X7s (2.7 & 3.0) have a height control unit on each wheel whereas the 4 Cylinder engines have 2 height sensors - one on each axle.

Other differences are that the V6 models have a separate suspension computer in addition to the one incorporated into the BHI. The 4 Cylinder engines just have the one in the BHI. The 6 Cylinder X7s have a similar system to the C6, without the AMVAR function implemented.

I mention this as it is something to consider parts wise....

The more concerning thing I would mention is the steering racks on these are prone to rusting pinions. I was on my third rack before I recently sold mine and others here are also on their second or third rack. There is a boot modification you can do (detailed on the forum), to help prevent water getting onto the pinion shaft and sitting there accelerating the rust. Once the rust goes below, it deforms the seal and rust contaminates the system. Replacement refurbished racks tend to be treated and coated to help prevent this and along with the mod and copious amounts of marine grease should see you ok.

Hi, and :welc: to the forum.

I cannot offer any advice re engines, but it is known that the steering racks develop leaks over time. It seems that the racks were built using a less than optimal quality of steel, the pinion slowly corrodes (as there is a cavity where water can accumulate), and then the fluid leaks past. In the UK (I know you are in New Zealand) there are companies who refurbish the steering racks, and some even chrome plate the pinion to protect it. Another way is to dump a load of waterproof grease over the pinion and then fit a gaiter to keep the grease in place. I cannot offer any advice as to how this is done.

Thanks guys, appreciate the quick replies! Have edited by comment and now reads as Exclusive.

The 3.0 is in Auckland and the plan is to get it checked over by a well known Citroen specialist and discuss with them parts availability and will discuss with them the rack issue.

I'm pretty set on getting a C5, just seeking guidance which road I should go down.

Strut replacements can be got from Europe (Poland) considerably cheaper than the dealer - but of course with shipping that may eat into the savings - but Citroen are now using the same struts as the 4 cylinder engines for replacement parts instead of the versions they would of originally shipped with as they consolidate stocks and supplies.
