Noise on startup?
I get an intermittent noise on startup. Sometimes disappears after a second or two, other times stays for 20-30 secs. Revving engine then seems to clear. Have had aux belt & tensioner belt replaced about 5k ago. Belt looks fine, but sound seems to be coming from the front of motor. Tensioner bounces around a little, but doesn't look abnormal - could it have failed so early? Any other ideas on what it could be? iid shows no faults.

Hi
Sounds like the starter motor is sticking , not loose is it ??? , seeing you’ve had the belts replaced and believe the starter motor has to be removed
But know the members here are more experienced

Have heard the same noise before, normally means the starter nose bush has collapsed.

Only had aux belt (not main) replaced 5k ago after previous bottom tensioner became faulty, so starter not removed. Replaced top tensioner at same time. Main belt was done 50k ago. Will remove belt and check torque on tensioners - visuallly they look fine.
Sometimes sound comes back while driving too. Have also noticed the air con compressor pump spins the whole time, does this normally happen? Could the ac pump be the problem?

Took off aux belt. Sound disappeared. Played with all the 'wheels' - alternator found to be turning very roughly. Issue found. Thx all

Tried a bunch of techniques to remove, ended up taking it out the bottom after removing intercooler pipe to give some clearance.

Easy job if you want to tackle it yourself.
Remove the top part of the fan cowl, it un-clips at each end. Viscous fan off, LEFT HAND THREAD! Use a 36mm open ended spanner & hammer, not a chisel & hammer like some ..kers. Probably not the kinda size most people have, so you may need to borrow or buy one (eBay link below) Position the spanner at 12 o'clock (you may need to turn the viscous 'nut' with the spanner).
Now for the fun part!
What your're going to do now is strike the other end of the spanner towards the coolant bottle (left hand thread) with a good hammer to undo the coupling. It should need a really good wack, a bit like swinging a baseball bat. Depending on how good your swing is, you may need a couple of attempts at this. You'll probably knock the spanner off a few times until you get you hand in. Once you cracked the 'nut', you can turn the fan by hand until the end of the thread. Make sure you hold the fan as you unscrew it to stop it dropping down. When you have it off, rest it in the bottom of the cowling and unplug the cable to allow removal.
It might be advisable to get an old towel or 2 to use as padding in the direction of the spanner to avoid accidental damage from a flying spanner..!!
Once you've got the fan out of the way, you need to use a 3/8 ratchet or lever bar to pull the aux belt tensioner back to release the belt. Make a note of the belt to pulley layout to make refitting it easier.
Next, remove the pump pulley. If they have the right bolts, then you'll need an E12 (Torx socket) to remove them. To stop the pulley moving, just get a phillips screwdriver or something similar and poke it through one of the holes on the pulley to hold against the block (don't worry, nothing to damage here)
Now you can get to the water pump. 8mm hex head and make a note of the 3 bolts in case they are different lengths.
Gold star if you loosen the fan in one hit. It took my 11yr old daughter 4 attempts!
It should take no more than an hour to change the pump.
