MikeT's C5r 1.6 hdi Estate

... leaving the caliper replacement for another day.

Found the energy and time to replace the caliper last week.
Gathered the relevant tools together and dragged them round to the car park. Got out the jack, axle stands, wheel-blocks from the shed, donned my overalls and rubber gloves and set about removing the front wheel.
Presented new caliper to familiarise myself with replacement and oh-oh! This isn't right. Well, in fact, yes it was right.... Front Right in fact, when I ordered Front Left caliper! Arghhh!

The silver lining being the seller offered a 50% discount for his "boxing error" if I wanted to keep the item which I happily accepted and put the discount towards ordering the correct part.

Meanwhile, I've begin to notice a vibration that too often occurs while accelerating through 30-40mph in either 4th or 5th. What could that be?

That was a shame Mike but serious kudos to the seller for his offerings

Playing with Lexia on my car yesterday, I noted the DPF was getting close to another auto-regen so decided to test the Forced Regen option as it was fully warmed up and unusally, with over half a tank of fuel to boot.

I was anxious for many reasons but it went suprisingly smoother than I'd anticipated. After a minute of non-action the rpms began to gently and smoothly increase to 4000rpm which it held for five minutes before slowly reducing back to idle. Observing the exhaust during this process I was slightly disappointed with the lack of fire and brimstone, the exhaust was surprisingly clean. However, on hard acceleration shortly afterwards, I noted quite a haze cloud in my mirror - presumably blowing out the ash? Additionally, instead of estimated 3% soot loading I've come to expect after an auto-regen, it read 0% this time. I put this down to the fact I normally drive below 3000rpm.

After the forced regen, lexia did report "Regeneration completed but with problems" With no further info, I hope it was due to the permanent passenger wing mirror heating element fault this car has.

Another pleasant side-effect of the above I noticed today when perusing lexiai live parameters;

The average distance bettween automatic regenerations were always reported to be about 330km. Today showing a soot loading of 53%, it reports I've covered well over 440km since the last regen!

Consequently, the average mpg is also on the rise

Now, coming up to service time (oil and filters) I'm going to drop the sump to examine the oil pick up. If I find it clogged, should I clean and refit, replace with new or tear out the mesh and forget it about forever more? I don't relish the idea of sump-dropping being a regular service task.

Ditto, re the turbo oil filter btw.

I would definitely remove the turbo oil feed filter - this alone will save the turbo. I wouldn't disturb the sump unless you have any issues. You will be able to tell if the pick up is blocking as the engine will rattle for a second or two at cold start, and when it gets worse will knock a bit at idle. If you ignore this long enough, eventually you will get to low oil pressure light. On our C4 I replaced the pick up at 69k when the turbo went, then we got low oil pressure at about 76k, so I cleaned the pick up. We got low oil pressure again at about 83k, so I ripped the strainer out. No problems since (now on 106k). I do oil changes at about 6-7k intervals to keep the crap down (it's due again!). It does use a bit of oil now, but that's not entirely surprising given the low oil pressure events. I took the turbo strainer out of the 307 at about 90k; now on 132k, not had to disturb the sump yet.

[MikeT]

I'm all for not bothering if there's no need. Perhaps if I, as you say, check the turbo oil filter first that would at least indicate the state of contaminants.

What are the advantages of a 1.6 engine of this type over the 110 2.0 8v?
Is it just that there may be more 1.6 around?

[MikeT]

Cost-wise, the road fund license. Currently £140pa. Fuel economy is pretty good too.

When I taxed my 2.0l C5 estate at the end of May it cost me £150.

Is this the MK1 you're quoting? That's pretty good. Although I did test drive a MK1, I was biased against the cosmetic looks. Driving it was fine, just don't like the external look of them one bit. Subjective, I know but I don't think I could've lived with it. The restyle is far more pleasing to me but each to their own.

[Hell Razor5543]

Yep, Mk1, but with the same wheels you have on your Mk2.

They are nice wheels - especially when they're clean.

True, but they are a real SOD to clean!!!

[lexi]

Yeah, mk1 here and £150 to tax. Need to be getting a lot more on fuel from a 1.6 hdi to justify the faff of FAP and cleaning sumps and injectors.
I do see more of the 1.6 up here for sale, but usually lots more miles. I only get about 45mpg on long runs mind. Always looking for the right estate up here.

I know the DPF is a bit of a bandaid but I think Citroen have done a damn good job of it as it's growing on me. I don't believe my engine is in the best state of tune (poor maintenance) but I'm slowly restoring that. MPG is showing promise with a best average of 56.4mpg @ just 5mph.
