So does what's on there now Dean, a straight-through pipe

It's got to be a good thought though if my MOT man gets a bit fidgety about it being sans cat...

I would stick with the straight through for now then Jim, put it in a few weeks early for its mot and if it fails then get a cat put on, he may not even notice, my garage didnt.

I found my TCT got very hot under the bonnet, no wonder the turbo's water cooled.

Steve

All petrol turbo's are water cooled due to higher egt.

They do Steve. Try an Activa! In my as yet limited experience the XM TCT runs cooler than an Activa but note the difference in radiator size. The XM one is huge against the Activa one...

If you think a TCT gets hots under the bonnet try a PRV V6!! With regards, Matthew T.

That would really put me off, I couldn't help thinking the TCT needed a bonnet vent like mercs have. No wonder it was warmed up in a mile or so.

I though the fast warm up of citroen engines was a deliberate design feature.
Minimises the period of poor emmission performance.

John

yes a lot of effort went into getting a fast warm up apparently, perfect on a frosty morning to compensate for those non working seat heaters

But seriously it was deliberate as John says and to minimise engine wear and tear. something that works very well indeed, mine will be blowing warm air through the heater in half a mile which is pretty good really.

Here's a good starter for ten, as Bamber might say...

What car requires half the front end dismantled to change an accumulator sphere?

A TCT XM of course

I bit the bullet this morning after recovering from my Activa Pre-MOT yesterday and got the nosecone off the XM so that I could pull the rads sufficiently far forward to reach the accumulator sphere..

A couple of issues emerged. The O/S wheelarch bumper mount has dissolved to nothing but all bits rescued and there's enough sound metal left to re-fabricate it. The N/S is perfect

The N/S bumper skirt captive nut tore out of the nosecone but again, a simple patch will sort that - no problem.

The steel bumper insert is a bit crusty but a coat of rust killer and a few coats of paint will sort that...

With the nose off and the rads pulled as far forward as possible, it was just possible to get a good strap around the accumulator and crack it off and ease it out.

Good job I did that job, the accumulator was ruptured and spilt a lovely amount of LHM. Not sure how it was sealing either as the old seal was badly crimped.

With the best I could muster, a centre sphere at around 45 bars has been used as a new accumulator and now the hydraulics are a lot happier so it was worth doing the job

I'm still curious to know if the FDV is entirely happy. It gently hisses continually unless steering assistance is needed. That's good as the hiss is the result of the steering pressure regulator operating and excess LHM being returned to the reservoir. The only thing I note is that assistance is available as soon as the engine is started and I'm not sure that's absolutely right - my old Sinker did not give steering assistance until the accumulator was fully charged and normal height reached...

That's enough for today, next jobs are to repair the bumper mounting and swap the transmission fluid...

Bizarrely, the ABS light has gone out

XMs - don't you just love 'em...
