107 / C1 / Aygo experiences?

I’ve a bit of experience with these, especially the Mk1, as I used to manage a Citroen dealership a dozen years ago, and now run a C1 as a daily. My partner has also had a couple, and my Dad has a Mk2 C1 currently.

Mk1 issues;

• Early neglected ones are starting to rot around the rear inner & outer sills.
• The petrol engine can suffer from piston slap and use oil - they’ll carry on running forever like this, though.
• Water pumps leak, it’s a cheap, easy repair though.
• Clutches aren’t particularly robust, they don’t last too long and tend to bite high. They’re an easy one to replace, though, and Exedy do a modified, uprated clutch which seems good.
• They suffer from water ingress into the interior via the high level brake light, rear lights, door & boot seals and door membranes. Don’t use silicone - it’s a bodge. Buy the uprated seal kit from X8R for around £130, I’ve fitted one of these and mine hasn’t leaked a drop, since.
• Later Mk1’s have a modified gear linkage and a nicer stereo with Bluetooth. This stereo however is impossible to replace for an aftermarket unit due to the weird wiring harness used (ask me how I know).
• Sometimes instrument packs fail and cause weird and wonderful electrical faults, quite a rare thing, though.

Regarding the Mk2, I strongly recommend avoiding the 1.2 EB wet belt engine. It’s economical and torquey, but predictably, the wet belt breaks up and blocks the oil pump. PSA are on about the fourth revision of the belt now. They need special tools to change, and while not as horrendous as the Ecoboost, still aren’t an especially nice job.

I sound full of doom and gloom, but they’re hardy little things that are very cheap to run, fun to drive (if somewhat slow) and easy to fix. I’d highly recommend them.
