CLLB statt CFFB in Sharan 7N | Posts 16+

While it doesn't directly address the issue, back when I had a problem engine in one of my many cars, a gauge for oil pressure and oil temperature was installed. This way, everything could be monitored... There used to be 52mm diameter gauges from VDO.

Also, you also learn how to start and warm up your engine correctly using the oil temperature gauge.

Unfortunately, sent too early... The CLLB has an oil pressure between 0.8 and 0.9 bar at an oil temperature of approximately 85°C in idle.

The values are within the acceptable range.

Start and in free-running mode: 0.6 Bar

Operating temperature at 2000 RPM 1.0 Bar

After a motor failure, one becomes very sensitive to everything, I would feel the same... especially when one has done the work oneself!

Can I find out what the cost of the time-appropriate repair was, approximately?

The engine oil temperature is displayed on the Sharan 7N.
I ordered a VDO gauge set for the oil pressure.

The oil pressure switch in the Sharan is not directly connected to the gauge. At least, the engine speed is also taken into account.
I don't know whether the oil temperature or the time also plays a role.
Below 1800 RPM, no oil pressure warning is issued, which can give the impression that there is no problem.

Based on this connection, I conclude that the old engine had a pressure of briefly below 0.35 bar (+- tolerance from the oil pressure switch). And that was at a speed of over 1,800 RPM. In this case, it is likely that a more fundamental problem is at play.

Hi,
The question is what "at the top of the engine block" is supposed to mean. Where is the switch located in the oil circuit diagram, compared to what?
The idea of integrated instruments is great, but I can't find a suitable space in the current models from the VW Group. For my old Audi 80 B4, the manufacturer offered an extra panel with three round instruments as a sporty version. Today, there are labels and an exhaust valve control . They offered this to me as a personalized extension, just when the diesel fraud was becoming a major issue. The ejaculation of Mr. Stadler and his entourage came to an end.

@ Rüdi

Used engine with 70,000 km, priced at 1,800,- with warranty.

The invoice from the mechanic is still coming. Due to the self-effort, it went relatively quickly.

In addition, there are costs for: clutch kit + double-mass flywheel, ZR kit, and other small parts.

I estimate that the entire project will cost approximately EUR 3,500 to 4,000.

@ Herbert

Due to the position of the pressure switch for reduced oil pressure, I suspect its integration into the circuit according to the diagram. I don't assume that one would have a separate oil channel solely for the switch - this wouldn't make technical sense either.

[Admin: Oil pressure switch >2bar is located near the oil pump, which provides reduced pressure to the ZK.]

Hello or Goodbye,
Where did you get the image from? RLF? The location after the filter is actually standard.

@Herbert

I have the image from "SSP403".

Specifically, in this case, CBAB is being treated. However, it is similar to CFFB and CLLB in its basic features.

Here is the position of the switch: Next to the tandem pump on the rear of the engine.

Hello,

Please be sure to respect all image copyrights.
Unfortunately, this is not the right way. Bestenfalls only own images.

Best regards, Rainer

Okay. Are there different SSP 403?

@Admin: Could you please elaborate on that? I am only familiar with the following components for this engine type: the oil overpressure valve (after the pump) and the oil pressure switch after the filter.

That's all that could be seen in the picture... 😃
I don't know. Maybe I made a typo with the 403. Please, due to legal risks, do not post images where the copyright belongs to others. 😉

The 403 already exists. However, it shows the oil circuit like the 410. The principle is the same for all: a pressure switch in the circuit after the filter. In my case, the switch is actually located on the right side, at the back of the cylinder head. Depending on the design of the inlet channels, it "senses" an oil pressure, which may be similar to the pressure near the ZK (cylinder head). The pressure should be at least 0.6 bar. The switching pressure is maintained by the RLF between 0.3 and 0.6 bar.
On the Audi 80 with the dynamic oil pressure control, there were two sensors on the oil filter flange, one for 0.25 bar and one for 0.9 bar.
