something is wrong with my golf

[RTechUK]

hi all, need ur help

i got golf mk4 1.8 20v turbo. I was on my way to hinckley today and noticed temperature guage shooted to far right and started to give me warning to check coolant, service manual and stop. I checked the coolant level which was alright, started car again and temperature was in middle. After half mile, temperature guage went up again and gave same warning, stopped again but couldn't figure out whats wrong. so called mechanic who came down and we brought car back to his workshop.

Spend all day today trying to fix it but its still the same. Tried replacing temperature switch and thermostat but didn't worked. Tomorrow plan is to check water body, radiator and head gaskit.

Anybody got any idea what could be the problem so i can resolve the issue. And worst part is I was on my way to R-tech for remap which couldn't be done cause of this

Sorry to hear your problem m8, Luck for you and your wallet (and me) it went prior to the remap.  When your ready to book in again just drop us a line m8.

Mine had same problem. Turned out to be water pump aswell.

Sickner with mine was it was 3 hours after I bought the car and got it home 

i would have been on the phone in that case telling them to collect the car and sort this out

yes push the button on the side of your wiper stalk

i know by pushing those buttons it shows different things i.e. total time or total distance

is it normal when it keeps on giving u such readings?
