What is the recommended replacement time to renew the timing chain on an Mpi? I do not see this specified in the manual or service booklet. How complex is the job and what else needs to be replaced? Does the engine take a special chain? My car has very low miles (under 28,000) but its starting to get old and I don't want it to snap while the engine is running and damage the engine.

A 28,000 mile engine will not need a new timing chain. They are normally replaced on a major engine rebuild. As long as you keep it serviced properly it should last you. Make sure you can get it on a diagnostic machine now and then just to keep the ECU sorted too

So there is no need to do a replacement due to age?

iv never know of a timing chain 'go'. its not the same a s changing the cam belt on regular intervals on a modern car. these chains don't need to be touched.
yes they can wear over very high mileage and put the cam timing out slightly, but I believe that the ecu can correct this.
but we are talking such high mileage that the engine would require a full overhaul anyway at this stage, not just the timing chain replacing!

If you had the motor out or the timing cover off for one reason of another, I would simply replace the chain tensioner pad. This is that the chain rides against and keeps tension on the chain to help eliminate excessive noise. They can wear a bit but not at 28k. I pulled my motor at 40k and mine still had plenty of life left.

also I am pretty sure the a-series does not have the issue of pistons and valves colliding if the timing belt were to snap so there shouldnt be an issue other than replacing the chain if it failed (but dont count me on that as its just what I have heard on here)

I had one snap on my old 998, it was rattling for a long time before and I had planned to change it the next day, it was fine after we replaced it as there is sufficient gap between the block and head. I don't know about 1275s though
