The pump on my 2006 coupe beshat it's breaches last year at 108k, luckily it was at the beginning of a long journey.
North West Surrey
Well I already posted about my E86.
But my daily 325i also has an N52 engine. That water pump died 6 months after I bought it.
Still it looks like it made it to 12 years and 135K miles as it's only ever been to main agents (15 visits in all) and neither of them had replaced a water pump! Maybe they last longer doing higher miles?

£227 for water pump, and two hours labour @£50ph at local Indy to fit. Seems like a no brainier for peace of mind. Never intend selling car, so booked it in.

If you don't have a receipt to show it there is no way of knowing. I think what would also be interesting to see on this poll is what percentage of N52K (black top engines) owners have had water pumps fail. There was some rumour around that the pump was modified for the N52K but the details are very sketchy.

My new to me E89 has a N52 motor with 61,000 miles on it.
How can I tell if the water pump is original or has been changed?
This might be total nonsense, however I seem to recall someone mentioning that from the factory, the bolts holding the waterpump in place have some blue (glue?) stuff on them. Chances are with a replaced pump this hasn't been done again, especially by an indy..

Anything bolted to the engine block on the N52 has bolts with a blue blob on the heads to identify them as single use aluminium bolts.
But I believe the pump kit from Pierburg comes with new bolts, and as they made the OEM pumps the new bolts might have blue on them too!
If anyone has done a DIY pump replacement they should know for sure.

Thank you - I'll have a look and see.
Another one to suffer, albeit at 142,000 miles (don't know if it was replaced earlier in its life by a previous owner but we have had the car for over 6 years).
Bought the Pierburg pump (11517586925, £249.59, comes with the one time use only bolts with it) and Mahle Behr TM1497 thermostat (£58.99 plastic unlike the original metal one) from bmwmotormec on ebay.
Had the car serviced (oil change, air filter, spark plugs replaced) at the same time as having the pump and thermostat replaced and total labour was £185.00 + vat from my local garage near Canterbury. So all in, price should be no more than £500 and I see plenty on here having it done for less. No issue identified with the thermostat, but replaced it as a preventative measure whilst the pump was out.

Around 120k and cost £1000 to fit at the dealer. Managed to limp it to the dealer which was only 5 miles away thankfully. it was on my list of things to do with my indy but was waiting for a cheaper insp1 to do at the same time. In the end i did an Insp2 followed 2x weeks later by the water pump. Lean times.

Probably not. I did get Sopers Lincoln to quote and prices below are RRP for OEM parts (with Soper's forum discount in brackets):
Water Pump £508.34 + vat (£549.01 incl VAT)
Screws £5.86 + vat (£6.34 incl VAT) [these come included with the Pierburg pattern part]
Thermostat £92.24 + vat (£99.22 incl VAT)
So just in parts alone, if you replace pump and thermostat at a non-forum friendly dealer it is £725.
Mr Tidy said:Just don't buy from BMW!
When mine died in 2015 my Indy paid over £500 for a pump from BMW.When the pump died on my 325i in 2018 he bought an OE Pierburg one elsewhere and charged me around £300 for the same part.
Indeed. Bought the Pierburg pump (11517586925, £249.59, comes with the one time use only bolts with it) and Mahle Behr TM1497 thermostat (£58.99, plastic unlike the original metal one) from bmwmotormec on ebay. £308.58 vs £725 is a lot better and I can see plenty on here have got better prices than that too.

No mistake. It wouldn't have been much cheaper at the Indy I use either. Sure the pump is a couple of hundred quid but it is quite awkward to get to - hence the labour. I was expecting it to cost that much so it wasn't too much of a shock (only to the wallet).

It's very easy to get to on the Z - nothing much needs removing at all for access apart from the undertray. Much easier than it is on the 3 series. Even the 15 min bleed afterwards is fully automatic while the mechanic goes off and has a cup of tea.
