Hi peeps!

So, my water pump finally failed on my 1.8t. Common problem, since the Bosch unit uses a plastic impeller. Anyway, had new one fitted (yay RAC warranty paying most of it!) and it's got the new metal impeller.

Anyway, since picking it up this afternoon (only dropped it off this morning) and having owned the car since Aug, why does it all of a sudden feel so powerfull?

Not complaining, but I don't understand why fixing the pump (only failed on Sun) has resulted in the car being more powerfull. I'd like to note that I have had it since Aug, so I am "used" to the power of it, and the first reaction of "OMG, this is quick compared to my old car" has kinda worn off. Since picking it up though, it seems like that first test drive at the dealers, where I knew it would be quicker and it was.....

Reckon the ECU combined with lots of sensor readings made it hold back to stop it blowing or anything?

Confused.... :confused:
 
You didn't have a 1.2 Ibiza as a courtesy car did you? :p

I remember once I went from a 1.2 Polo courtesy car to a 3.0l Omega. My god it felt quick!
 
Car is more than 3 years old.

Has more than 30k on it (just).

RAC Warranty was free, they pay for all parts and for the first £36/ph labour.

Seat are £69/ph, hence the amount I have to pay.

Water pump at this Seat garage takes 2.5 hours, no proper dealer charges in half hour slots.

Water pump was £29, coolant was £5.

I needed the car back ASAP (can't argue with same day service really).

Total cost was £270. (I pay £136)

Brother works for Skoda/Saab/Alfa, quoted £400 to a "normal" customer for same job on Fabia VRS. (previously worked for Audi/WV, you don't want to know the labour rate there!!!!)


Any more questions? :p

Turbos are effected by heat especially so poor water flow reduced the power prehaps ?

I think they probably reset the ECU also since it would be standard practise to disconnect electrics during the job.

If the car has sensors for this water pump and the ecu picked up a fault code then it might have a limp home mode with reduced power. Does this model have a knock sensor, what octane does it take/prefer..
 
Have asked on SeatCupra.net. Only suggestion is that the ECU adaptions have been reset.

I presume there is a flow sensor, hence when the pump died I got a flashing red light, despite just starting the car at 8am and it was below freezing outside.

I am wondering if the pump has slowly died, hence not noticing the power loss over a longer period. When the pump died completely, the flow sensor would notice?

My other thought is that the MAF may be up the spout and the ECU has been adjusting the fuel/air mix accordingly. I know for a fact that the limp mode/light doesn't alway come on for this and only VAG Com could let you get readings to determine if it is indeed faulty.

Anyway, seems ok at the moment, will keep an eye on it. If it reverts back to normal, time to get Vag Com!
 
When my ecu has a fault code, it lights up a sign on the dashboard. Then if I peel back the carpet to check the ecu, it flashes 17 times which corresponds to a certain fault. Not sure if newer cars are this easy to read or specialist equipment would be needed.
