I am probably not the only one who would like to see a cost breakdown...it seems very expensive to get what you got...

Honestly I've lost count and don't have a breakdown sheet but the most costly was the head rebuild at $600.

The complete engine was only $200 from a pick & pull and the AW-50-42LE gearbox was $150....but this was a self-pull. I still have a 20 valve wide-port head in great condition that I'm sure will fetch $200 on the used market. Most of the parts came from FCP Groton (even the orders they botched) so you can get your own idea of pricing.

Blasted O2 sensor was $165 landed (only $5 cheaper at the local boneyard due to them only covering 2 model years)

Got another ETM from a S80T6 last week (about $160 landed) from eBay and she runs fine, idle is smooth and consistent, no ETS lights. An ETM sweep test through Vida gets me around 3.5% variance b/w front and rear throttle position sensors. Compared to the rebuilds I've done with new sensors that is high but within Volvo's tolerance of 13%. The first one I rebuilt had only 0.16% variation and the second 1.1% .

I figure if she's good for 5 years with minimal maintenance the fun and learning have paid for themselves....but who knows as I'm really hankering for a C70 lately. I may sell this and keep the 960 wagon.

So as I mentioned the driver's seat was toast and I found various items from a '96 850GLT with 70K miles for this '99V70.

Only problem is the SRS connector going to the '99 seat is now left hanging as there is no airbag connector on earlier seats and this creates a SRS light.

When measuring across the passenger side connector (disconnected, of course) it's almost a short like 0.3ohms or less. I'm inclined to believe it may be a fusible link that was meant to be in the '99 seats.

Has anyone done an earlier seat swap into a '99 and overcome the dangling connector?

I'm going to try a 1/4 watt 0.3ohm resistor across the terminals and see if that helps. Any harm in doing this?

Well since no-one has tried fitting a '96 850 seat into a '99-2000 V70 I'll leave that one for another time

Today I had another success with what I thought was a ABS problem. Forum member Matty Moo kindly sent me a rebuilt ABS unit which was great as I wanted to eliminate this from why the car gave a P1027 (speed sensor) fault and also not have any problems with this in the future.

However this didn't fix the P1027 code

I was silly enough NOT to have swapped the speed sensor from the '99 AW-50-42 in to the '96 trans which is used apparently while the car is in REVERSE ONLY. The ABS wheel ring is used for FORWARD MOTION and that's why the P1027 can be a bad ABS unit (but only if this occurs while moving forward) So once the speed sensor was swapped no more P1027. I was quite lucky as I was testing the car in the narrow laneway behind my home and had to reverse to come back so the problem only happened on the return trip.

I've seen the reference to blocking the intake open to get accurate readings. I've never done that but since I do the readings solo (generally) I just put the pedal to the floor and assume the valve is fully open. Am I missing something? (Mostly I look for variances between the cylinders).

As the '99s are an ETM car the throttle plate will close in some cars 6 secs after the ignition is started. If NA they close to around 32 degrees and if turbo about 24 degrees.

In this case jimmy57 may have thought the throttle plate was jammed shut as can happen with some of these electronic throttle units when they're extremely dirty.

If non ETM (throttle cable) just do as you've been doing and you'll be fine, Sim.

Posted a vid today on how she turned out.

Just afew more details like windscreen, window switches and coolant top up; nothing too serious..

I almost gave up and started advertising her for parts. If I had successfully removed that passenger window motor for a interested buyer she would be scrap right now!! Fortunately for the car I couldn't remove it.

It ended with the maximum time my phone would allow so sorry I didn't get to say bye. Thanks for looking.

Today I went for the first drive at around 6:00pm after getting a temporary permit from our local roads authority for 28 days.

I have a bearing or shaft noise which increases with vehicle speed. The engine began to miss (I'll have to replace the coils to narrow it down or check fuel injectors as the fuel in the tank is now 2 years old) ) and I still have a P1027 (read from an Autel scanner) which is something to do with a speed sensor read off the TCM.

After hooking up to Vida it seems there's a code related to the engine speed sensor on the transmission.

Does this mean the speed sensor on the trans (not engine) may be faulty or badly connected?

Anyone have any ideas? Should I revisit the ABS module first?

Just to close this thread and provide a solution to the final problem I had it ended up being the speed sensors on the gearbox weren't both swapped out when I used an 850 gearbox in this '99 V70.

The speed sensor problem was solved then a driver T boned the car about a month later

I'm still not over it
